Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540756, here are decompositions:
- 29 + 31540727 = 31540756
- 47 + 31540709 = 31540756
- 113 + 31540643 = 31540756
- 227 + 31540529 = 31540756
- 257 + 31540499 = 31540756
- 263 + 31540493 = 31540756
- 593 + 31540163 = 31540756
- 647 + 31540109 = 31540756
Showing the first eight; more decompositions exist.
