Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31490762, here are decompositions:
- 103 + 31490659 = 31490762
- 139 + 31490623 = 31490762
- 283 + 31490479 = 31490762
- 379 + 31490383 = 31490762
- 439 + 31490323 = 31490762
- 463 + 31490299 = 31490762
- 613 + 31490149 = 31490762
- 631 + 31490131 = 31490762
Showing the first eight; more decompositions exist.
