Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31457882, here are decompositions:
- 13 + 31457869 = 31457882
- 61 + 31457821 = 31457882
- 139 + 31457743 = 31457882
- 163 + 31457719 = 31457882
- 241 + 31457641 = 31457882
- 271 + 31457611 = 31457882
- 433 + 31457449 = 31457882
- 499 + 31457383 = 31457882
Showing the first eight; more decompositions exist.
