Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542460, here are decompositions:
- 3 + 31542457 = 31542460
- 23 + 31542437 = 31542460
- 41 + 31542419 = 31542460
- 83 + 31542377 = 31542460
- 101 + 31542359 = 31542460
- 137 + 31542323 = 31542460
- 179 + 31542281 = 31542460
- 227 + 31542233 = 31542460
Showing the first eight; more decompositions exist.
