Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549008, here are decompositions:
- 11 + 31548997 = 31549008
- 47 + 31548961 = 31549008
- 137 + 31548871 = 31549008
- 151 + 31548857 = 31549008
- 191 + 31548817 = 31549008
- 241 + 31548767 = 31549008
- 251 + 31548757 = 31549008
- 269 + 31548739 = 31549008
Showing the first eight; more decompositions exist.
