Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 495866, here are decompositions:

37 + 495829 = 495866
67 + 495799 = 495866
79 + 495787 = 495866
97 + 495769 = 495866
109 + 495757 = 495866
199 + 495667 = 495866
229 + 495637 = 495866
277 + 495589 = 495866

Showing the first eight; more decompositions exist.
