Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542008, here are decompositions:
- 7 + 31542001 = 31542008
- 19 + 31541989 = 31542008
- 31 + 31541977 = 31542008
- 37 + 31541971 = 31542008
- 109 + 31541899 = 31542008
- 139 + 31541869 = 31542008
- 151 + 31541857 = 31542008
- 181 + 31541827 = 31542008
Showing the first eight; more decompositions exist.
