Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 56818, here are decompositions:
- 5 + 56813 = 56818
- 11 + 56807 = 56818
- 71 + 56747 = 56818
- 107 + 56711 = 56818
- 131 + 56687 = 56818
- 137 + 56681 = 56818
- 227 + 56591 = 56818
- 317 + 56501 = 56818
Showing the first eight; more decompositions exist.
