Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536656, here are decompositions:
- 43 + 31536613 = 31536656
- 127 + 31536529 = 31536656
- 157 + 31536499 = 31536656
- 433 + 31536223 = 31536656
- 607 + 31536049 = 31536656
- 673 + 31535983 = 31536656
- 709 + 31535947 = 31536656
- 829 + 31535827 = 31536656
Showing the first eight; more decompositions exist.
