Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543110, here are decompositions:
- 7 + 31543103 = 31543110
- 31 + 31543079 = 31543110
- 41 + 31543069 = 31543110
- 43 + 31543067 = 31543110
- 101 + 31543009 = 31543110
- 139 + 31542971 = 31543110
- 167 + 31542943 = 31543110
- 173 + 31542937 = 31543110
Showing the first eight; more decompositions exist.
