Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525816, here are decompositions:
- 5 + 31525811 = 31525816
- 17 + 31525799 = 31525816
- 29 + 31525787 = 31525816
- 53 + 31525763 = 31525816
- 167 + 31525649 = 31525816
- 227 + 31525589 = 31525816
- 263 + 31525553 = 31525816
- 317 + 31525499 = 31525816
Showing the first eight; more decompositions exist.
