Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 493518, here are decompositions:

37 + 493481 = 493518
61 + 493457 = 493518
71 + 493447 = 493518
149 + 493369 = 493518
167 + 493351 = 493518
227 + 493291 = 493518
239 + 493279 = 493518
241 + 493277 = 493518

Showing the first eight; more decompositions exist.
