Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 495628, here are decompositions:

11 + 495617 = 495628
17 + 495611 = 495628
41 + 495587 = 495628
59 + 495569 = 495628
71 + 495557 = 495628
101 + 495527 = 495628
137 + 495491 = 495628
167 + 495461 = 495628

Showing the first eight; more decompositions exist.
