Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525812, here are decompositions:
- 13 + 31525799 = 31525812
- 29 + 31525783 = 31525812
- 41 + 31525771 = 31525812
- 89 + 31525723 = 31525812
- 113 + 31525699 = 31525812
- 163 + 31525649 = 31525812
- 211 + 31525601 = 31525812
- 223 + 31525589 = 31525812
Showing the first eight; more decompositions exist.
