Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525858, here are decompositions:
- 17 + 31525841 = 31525858
- 41 + 31525817 = 31525858
- 47 + 31525811 = 31525858
- 59 + 31525799 = 31525858
- 71 + 31525787 = 31525858
- 251 + 31525607 = 31525858
- 257 + 31525601 = 31525858
- 269 + 31525589 = 31525858
Showing the first eight; more decompositions exist.
