Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31509536, here are decompositions:
- 7 + 31509529 = 31509536
- 13 + 31509523 = 31509536
- 67 + 31509469 = 31509536
- 103 + 31509433 = 31509536
- 193 + 31509343 = 31509536
- 199 + 31509337 = 31509536
- 229 + 31509307 = 31509536
- 367 + 31509169 = 31509536
Showing the first eight; more decompositions exist.
