Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567536, here are decompositions:
- 23 + 31567513 = 31567536
- 107 + 31567429 = 31567536
- 109 + 31567427 = 31567536
- 139 + 31567397 = 31567536
- 167 + 31567369 = 31567536
- 223 + 31567313 = 31567536
- 239 + 31567297 = 31567536
- 257 + 31567279 = 31567536
Showing the first eight; more decompositions exist.
