Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525748, here are decompositions:
- 31 + 31525717 = 31525748
- 61 + 31525687 = 31525748
- 97 + 31525651 = 31525748
- 139 + 31525609 = 31525748
- 181 + 31525567 = 31525748
- 211 + 31525537 = 31525748
- 271 + 31525477 = 31525748
- 487 + 31525261 = 31525748
Showing the first eight; more decompositions exist.
