Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 495666, here are decompositions:

19 + 495647 = 495666
29 + 495637 = 495666
37 + 495629 = 495666
47 + 495619 = 495666
53 + 495613 = 495666
79 + 495587 = 495666
97 + 495569 = 495666
103 + 495563 = 495666

Showing the first eight; more decompositions exist.
