Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542182, here are decompositions:
- 19 + 31542163 = 31542182
- 79 + 31542103 = 31542182
- 151 + 31542031 = 31542182
- 181 + 31542001 = 31542182
- 193 + 31541989 = 31542182
- 211 + 31541971 = 31542182
- 283 + 31541899 = 31542182
- 313 + 31541869 = 31542182
Showing the first eight; more decompositions exist.
