Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525968, here are decompositions:
- 11 + 31525957 = 31525968
- 17 + 31525951 = 31525968
- 41 + 31525927 = 31525968
- 59 + 31525909 = 31525968
- 79 + 31525889 = 31525968
- 127 + 31525841 = 31525968
- 151 + 31525817 = 31525968
- 157 + 31525811 = 31525968
Showing the first eight; more decompositions exist.
