Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525864, here are decompositions:
- 23 + 31525841 = 31525864
- 47 + 31525817 = 31525864
- 53 + 31525811 = 31525864
- 101 + 31525763 = 31525864
- 257 + 31525607 = 31525864
- 263 + 31525601 = 31525864
- 311 + 31525553 = 31525864
- 443 + 31525421 = 31525864
Showing the first eight; more decompositions exist.
