Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 495640, here are decompositions:

3 + 495637 = 495640
11 + 495629 = 495640
23 + 495617 = 495640
29 + 495611 = 495640
53 + 495587 = 495640
71 + 495569 = 495640
83 + 495557 = 495640
113 + 495527 = 495640

Showing the first eight; more decompositions exist.
