Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 495678, here are decompositions:

11 + 495667 = 495678
31 + 495647 = 495678
41 + 495637 = 495678
59 + 495619 = 495678
61 + 495617 = 495678
67 + 495611 = 495678
89 + 495589 = 495678
107 + 495571 = 495678

Showing the first eight; more decompositions exist.
