Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31508590, here are decompositions:
- 11 + 31508579 = 31508590
- 23 + 31508567 = 31508590
- 41 + 31508549 = 31508590
- 83 + 31508507 = 31508590
- 137 + 31508453 = 31508590
- 173 + 31508417 = 31508590
- 227 + 31508363 = 31508590
- 359 + 31508231 = 31508590
Showing the first eight; more decompositions exist.
