Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 495642, here are decompositions:

5 + 495637 = 495642
13 + 495629 = 495642
23 + 495619 = 495642
29 + 495613 = 495642
31 + 495611 = 495642
53 + 495589 = 495642
71 + 495571 = 495642
73 + 495569 = 495642

Showing the first eight; more decompositions exist.
