Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31511590, here are decompositions:
- 41 + 31511549 = 31511590
- 53 + 31511537 = 31511590
- 107 + 31511483 = 31511590
- 113 + 31511477 = 31511590
- 167 + 31511423 = 31511590
- 263 + 31511327 = 31511590
- 269 + 31511321 = 31511590
- 359 + 31511231 = 31511590
Showing the first eight; more decompositions exist.
