Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542056, here are decompositions:
- 19 + 31542037 = 31542056
- 43 + 31542013 = 31542056
- 67 + 31541989 = 31542056
- 79 + 31541977 = 31542056
- 157 + 31541899 = 31542056
- 163 + 31541893 = 31542056
- 199 + 31541857 = 31542056
- 229 + 31541827 = 31542056
Showing the first eight; more decompositions exist.
