Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545462, here are decompositions:
- 23 + 31545439 = 31545462
- 61 + 31545401 = 31545462
- 71 + 31545391 = 31545462
- 83 + 31545379 = 31545462
- 89 + 31545373 = 31545462
- 131 + 31545331 = 31545462
- 139 + 31545323 = 31545462
- 163 + 31545299 = 31545462
Showing the first eight; more decompositions exist.
