Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 495818, here are decompositions:

19 + 495799 = 495818
31 + 495787 = 495818
61 + 495757 = 495818
67 + 495751 = 495818
139 + 495679 = 495818
151 + 495667 = 495818
181 + 495637 = 495818
199 + 495619 = 495818

Showing the first eight; more decompositions exist.
