Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43518, here are decompositions:

19 + 43499 = 43518
31 + 43487 = 43518
37 + 43481 = 43518
61 + 43457 = 43518
67 + 43451 = 43518
107 + 43411 = 43518
127 + 43391 = 43518
197 + 43321 = 43518

Showing the first eight; more decompositions exist.
