Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525966, here are decompositions:
- 47 + 31525919 = 31525966
- 53 + 31525913 = 31525966
- 149 + 31525817 = 31525966
- 167 + 31525799 = 31525966
- 179 + 31525787 = 31525966
- 317 + 31525649 = 31525966
- 359 + 31525607 = 31525966
- 467 + 31525499 = 31525966
Showing the first eight; more decompositions exist.
