Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 495660, here are decompositions:

13 + 495647 = 495660
23 + 495637 = 495660
31 + 495629 = 495660
41 + 495619 = 495660
43 + 495617 = 495660
47 + 495613 = 495660
71 + 495589 = 495660
73 + 495587 = 495660

Showing the first eight; more decompositions exist.
