Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525990, here are decompositions:
- 71 + 31525919 = 31525990
- 101 + 31525889 = 31525990
- 149 + 31525841 = 31525990
- 173 + 31525817 = 31525990
- 179 + 31525811 = 31525990
- 191 + 31525799 = 31525990
- 227 + 31525763 = 31525990
- 383 + 31525607 = 31525990
Showing the first eight; more decompositions exist.
