Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 495684, here are decompositions:

5 + 495679 = 495684
17 + 495667 = 495684
37 + 495647 = 495684
47 + 495637 = 495684
67 + 495617 = 495684
71 + 495613 = 495684
73 + 495611 = 495684
97 + 495587 = 495684

Showing the first eight; more decompositions exist.
