Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525688, here are decompositions:
- 31 + 31525657 = 31525688
- 37 + 31525651 = 31525688
- 79 + 31525609 = 31525688
- 151 + 31525537 = 31525688
- 199 + 31525489 = 31525688
- 211 + 31525477 = 31525688
- 241 + 31525447 = 31525688
- 409 + 31525279 = 31525688
Showing the first eight; more decompositions exist.
