Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525838, here are decompositions:
- 61 + 31525777 = 31525838
- 67 + 31525771 = 31525838
- 139 + 31525699 = 31525838
- 151 + 31525687 = 31525838
- 181 + 31525657 = 31525838
- 229 + 31525609 = 31525838
- 271 + 31525567 = 31525838
- 349 + 31525489 = 31525838
Showing the first eight; more decompositions exist.
