Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525660, here are decompositions:
- 3 + 31525657 = 31525660
- 11 + 31525649 = 31525660
- 53 + 31525607 = 31525660
- 59 + 31525601 = 31525660
- 71 + 31525589 = 31525660
- 107 + 31525553 = 31525660
- 239 + 31525421 = 31525660
- 263 + 31525397 = 31525660
Showing the first eight; more decompositions exist.
