Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484960, here are decompositions:
- 19 + 31484941 = 31484960
- 97 + 31484863 = 31484960
- 139 + 31484821 = 31484960
- 163 + 31484797 = 31484960
- 313 + 31484647 = 31484960
- 457 + 31484503 = 31484960
- 499 + 31484461 = 31484960
- 547 + 31484413 = 31484960
Showing the first eight; more decompositions exist.
