Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 495998, here are decompositions:

31 + 495967 = 495998
67 + 495931 = 495998
199 + 495799 = 495998
211 + 495787 = 495998
229 + 495769 = 495998
241 + 495757 = 495998
331 + 495667 = 495998
379 + 495619 = 495998

Showing the first eight; more decompositions exist.
