If it's a prediction run, you don't know what marathon pace is currently...
Generally speaking you go into a marathon with SOME idea as to how fast you're going to go for 26.2 miles. I'm sure you've seen Ryan Hall and other elite marathoners checking their splits EVERY mile to maintain "Goal pace." The OP can clearly use the prediction run to give himself an IDEA of what pace he should run judging how hard those 10 miles will feel.
The original post needs to provide more info i.e., what did he run the days leading up to the easy 21 miler? What was the terrain, temperature, etc. Easy is also a very relative term. To the original post, contact someone experienced directly if you are serious about this.

Read up Daniels...

I looked up Daniels Running Formula pace for easy run. 6:40 gives you a VDOT of 68. I went to a corresponding chart and looked at associated times for a VDOT of 68. The ones I listed are what Daniel's prescribes. If he can run a 10k or a 1/2 marathon in those times he is capable of running 2:27. Lot of what-ifs, but gotta trust Daniels... he's a Doctor.
Daniels I trust. You not so much. Because you aren't doing it right. You even quoted me and then completely missed the point.
You don't look up an EASY RUN time to get your Daniels paces. There's a reason for that. The word "easy" is just too vague.
Instead you run a time trial or a race. As fast as you can cover a given distance in a given time and THEN you get your paces.
the link (in thought to Daniels) is a correct approach based on the information given.
if you download Daniels' training tables:
http://www.electricblues.com/html/runpro.html
(you can trust it the link), it suggests, based on keeping an easy run at 6:40 pace, a marathon in the range from 2:25 to 2:33. all things being equal.
Based on all the information given at this point, I would guess (if the marathon is paced properly) that the OP could run 2:31:27.83.
3:34
