Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525828, here are decompositions:
- 11 + 31525817 = 31525828
- 17 + 31525811 = 31525828
- 29 + 31525799 = 31525828
- 41 + 31525787 = 31525828
- 179 + 31525649 = 31525828
- 227 + 31525601 = 31525828
- 239 + 31525589 = 31525828
- 431 + 31525397 = 31525828
Showing the first eight; more decompositions exist.
