Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525918, here are decompositions:
- 5 + 31525913 = 31525918
- 29 + 31525889 = 31525918
- 101 + 31525817 = 31525918
- 107 + 31525811 = 31525918
- 131 + 31525787 = 31525918
- 269 + 31525649 = 31525918
- 311 + 31525607 = 31525918
- 317 + 31525601 = 31525918
Showing the first eight; more decompositions exist.
