Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 493540, here are decompositions:

17 + 493523 = 493540
59 + 493481 = 493540
83 + 493457 = 493540
107 + 493433 = 493540
137 + 493403 = 493540
227 + 493313 = 493540
239 + 493301 = 493540
263 + 493277 = 493540

Showing the first eight; more decompositions exist.
