Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540712, here are decompositions:
- 3 + 31540709 = 31540712
- 13 + 31540699 = 31540712
- 19 + 31540693 = 31540712
- 43 + 31540669 = 31540712
- 61 + 31540651 = 31540712
- 139 + 31540573 = 31540712
- 211 + 31540501 = 31540712
- 223 + 31540489 = 31540712
Showing the first eight; more decompositions exist.
