Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539726, here are decompositions:
- 13 + 31539713 = 31539726
- 19 + 31539707 = 31539726
- 67 + 31539659 = 31539726
- 83 + 31539643 = 31539726
- 139 + 31539587 = 31539726
- 157 + 31539569 = 31539726
- 227 + 31539499 = 31539726
- 313 + 31539413 = 31539726
Showing the first eight; more decompositions exist.
