Find non-prime, win beer cozy

I flipped through Douglas Copeland's book JPod this afternoon and noticed this passage:
Evil Mark stood up in the middle of the afternoon and said "I'm about to hand out sheets listing the 8,363 prime numbers between 10,000 and 100,000. Embedded in this list is one non-prime. First person to find that non-prime number wins my Family Guy promotional sixteen-ounce beer cozy."
In less than five minutes I won.
FUN FACT: any even number can be made by adding together two primes.
The next several pages contained lots of large numbers. The reference to Goldbach's Conjecture might suggest that there is an even number somewhere in the list, but that would seem a comedown from the guy who once encoded a passage in binary.

Any ideas?
