Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12528, here are decompositions:
- 11 + 12517 = 12528
- 17 + 12511 = 12528
- 31 + 12497 = 12528
- 37 + 12491 = 12528
- 41 + 12487 = 12528
- 71 + 12457 = 12528
- 107 + 12421 = 12528
- 127 + 12401 = 12528
Showing the first eight; more decompositions exist.
