Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525808, here are decompositions:
- 31 + 31525777 = 31525808
- 37 + 31525771 = 31525808
- 109 + 31525699 = 31525808
- 151 + 31525657 = 31525808
- 157 + 31525651 = 31525808
- 199 + 31525609 = 31525808
- 241 + 31525567 = 31525808
- 271 + 31525537 = 31525808
Showing the first eight; more decompositions exist.
