Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525870, here are decompositions:
- 29 + 31525841 = 31525870
- 53 + 31525817 = 31525870
- 59 + 31525811 = 31525870
- 71 + 31525799 = 31525870
- 83 + 31525787 = 31525870
- 107 + 31525763 = 31525870
- 263 + 31525607 = 31525870
- 269 + 31525601 = 31525870
Showing the first eight; more decompositions exist.
