Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 495810, here are decompositions:

11 + 495799 = 495810
13 + 495797 = 495810
19 + 495791 = 495810
23 + 495787 = 495810
37 + 495773 = 495810
41 + 495769 = 495810
53 + 495757 = 495810
59 + 495751 = 495810

Showing the first eight; more decompositions exist.
