Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525690, here are decompositions:
- 3 + 31525687 = 31525690
- 41 + 31525649 = 31525690
- 83 + 31525607 = 31525690
- 89 + 31525601 = 31525690
- 101 + 31525589 = 31525690
- 137 + 31525553 = 31525690
- 191 + 31525499 = 31525690
- 269 + 31525421 = 31525690
Showing the first eight; more decompositions exist.
