Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609246, here are decompositions:
- 17 + 31609229 = 31609246
- 23 + 31609223 = 31609246
- 167 + 31609079 = 31609246
- 197 + 31609049 = 31609246
- 293 + 31608953 = 31609246
- 353 + 31608893 = 31609246
- 359 + 31608887 = 31609246
- 467 + 31608779 = 31609246
Showing the first eight; more decompositions exist.
