Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545470, here are decompositions:
- 31 + 31545439 = 31545470
- 79 + 31545391 = 31545470
- 97 + 31545373 = 31545470
- 127 + 31545343 = 31545470
- 139 + 31545331 = 31545470
- 373 + 31545097 = 31545470
- 379 + 31545091 = 31545470
- 409 + 31545061 = 31545470
Showing the first eight; more decompositions exist.
