Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489536, here are decompositions:
- 17 + 31489519 = 31489536
- 47 + 31489489 = 31489536
- 73 + 31489463 = 31489536
- 103 + 31489433 = 31489536
- 109 + 31489427 = 31489536
- 137 + 31489399 = 31489536
- 173 + 31489363 = 31489536
- 257 + 31489279 = 31489536
Showing the first eight; more decompositions exist.
