Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 495664, here are decompositions:

17 + 495647 = 495664
47 + 495617 = 495664
53 + 495611 = 495664
101 + 495563 = 495664
107 + 495557 = 495664
137 + 495527 = 495664
173 + 495491 = 495664
227 + 495437 = 495664

Showing the first eight; more decompositions exist.
