Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 495688, here are decompositions:

41 + 495647 = 495688
59 + 495629 = 495688
71 + 495617 = 495688
101 + 495587 = 495688
131 + 495557 = 495688
197 + 495491 = 495688
227 + 495461 = 495688
239 + 495449 = 495688

Showing the first eight; more decompositions exist.
