Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525822, here are decompositions:
- 5 + 31525817 = 31525822
- 11 + 31525811 = 31525822
- 23 + 31525799 = 31525822
- 59 + 31525763 = 31525822
- 173 + 31525649 = 31525822
- 233 + 31525589 = 31525822
- 269 + 31525553 = 31525822
- 401 + 31525421 = 31525822
Showing the first eight; more decompositions exist.
