Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527972, here are decompositions:
- 5 + 31527967 = 31527972
- 31 + 31527941 = 31527972
- 41 + 31527931 = 31527972
- 59 + 31527913 = 31527972
- 191 + 31527781 = 31527972
- 263 + 31527709 = 31527972
- 269 + 31527703 = 31527972
- 271 + 31527701 = 31527972
Showing the first eight; more decompositions exist.
