Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 495278, here are decompositions:

37 + 495241 = 495278
67 + 495211 = 495278
79 + 495199 = 495278
97 + 495181 = 495278
127 + 495151 = 495278
139 + 495139 = 495278
211 + 495067 = 495278
241 + 495037 = 495278

Showing the first eight; more decompositions exist.
