Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 495680, here are decompositions:

13 + 495667 = 495680
43 + 495637 = 495680
61 + 495619 = 495680
67 + 495613 = 495680
109 + 495571 = 495680
223 + 495457 = 495680
337 + 495343 = 495680
373 + 495307 = 495680

Showing the first eight; more decompositions exist.
