Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542616, here are decompositions:
- 3 + 31542613 = 31542616
- 29 + 31542587 = 31542616
- 107 + 31542509 = 31542616
- 137 + 31542479 = 31542616
- 179 + 31542437 = 31542616
- 197 + 31542419 = 31542616
- 239 + 31542377 = 31542616
- 257 + 31542359 = 31542616
Showing the first eight; more decompositions exist.
