Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43540, here are decompositions:

23 + 43517 = 43540
41 + 43499 = 43540
53 + 43487 = 43540
59 + 43481 = 43540
83 + 43457 = 43540
89 + 43451 = 43540
113 + 43427 = 43540
137 + 43403 = 43540

Showing the first eight; more decompositions exist.
