4 then - if 1 isn't a prime, then 1+4 doesn't count.
EDIT - should have been 1+3, doh!
3 0 Reply2+2
16 0 ReplyJesus, I forgot 2 was a prime, what a dolt.

1+4=5 not 4 and 4 isn't prime either, so idk what you meant. 4 is the sum of two primes 2+2, which I thought was what you were asking at first.
4 0 ReplyI screwed up twice here. Forgot 2 was a prime somehow.
1+4 was just a typo, meant 1+3.

1+4 is 5 though.
4 0 ReplyYeah, typo. But I was wrong anyway! :-)
