Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545560, here are decompositions:
- 61 + 31545499 = 31545560
- 73 + 31545487 = 31545560
- 181 + 31545379 = 31545560
- 229 + 31545331 = 31545560
- 349 + 31545211 = 31545560
- 379 + 31545181 = 31545560
- 463 + 31545097 = 31545560
- 499 + 31545061 = 31545560
Showing the first eight; more decompositions exist.
