Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541122, here are decompositions:
- 5 + 31541117 = 31541122
- 71 + 31541051 = 31541122
- 83 + 31541039 = 31541122
- 101 + 31541021 = 31541122
- 131 + 31540991 = 31541122
- 251 + 31540871 = 31541122
- 443 + 31540679 = 31541122
- 479 + 31540643 = 31541122
Showing the first eight; more decompositions exist.
