Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525608, here are decompositions:
- 5 + 31525603 = 31525608
- 7 + 31525601 = 31525608
- 19 + 31525589 = 31525608
- 41 + 31525567 = 31525608
- 71 + 31525537 = 31525608
- 109 + 31525499 = 31525608
- 131 + 31525477 = 31525608
- 211 + 31525397 = 31525608
Showing the first eight; more decompositions exist.
