Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545882, here are decompositions:
- 23 + 31545859 = 31545882
- 41 + 31545841 = 31545882
- 139 + 31545743 = 31545882
- 241 + 31545641 = 31545882
- 271 + 31545611 = 31545882
- 283 + 31545599 = 31545882
- 383 + 31545499 = 31545882
- 443 + 31545439 = 31545882
Showing the first eight; more decompositions exist.
