Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545512, here are decompositions:
- 13 + 31545499 = 31545512
- 43 + 31545469 = 31545512
- 73 + 31545439 = 31545512
- 139 + 31545373 = 31545512
- 181 + 31545331 = 31545512
- 331 + 31545181 = 31545512
- 421 + 31545091 = 31545512
- 463 + 31545049 = 31545512
Showing the first eight; more decompositions exist.
