Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 495908, here are decompositions:

31 + 495877 = 495908
79 + 495829 = 495908
109 + 495799 = 495908
139 + 495769 = 495908
151 + 495757 = 495908
157 + 495751 = 495908
229 + 495679 = 495908
241 + 495667 = 495908

Showing the first eight; more decompositions exist.
