Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 495938, here are decompositions:

7 + 495931 = 495938
61 + 495877 = 495938
109 + 495829 = 495938
139 + 495799 = 495938
151 + 495787 = 495938
181 + 495757 = 495938
271 + 495667 = 495938
349 + 495589 = 495938

Showing the first eight; more decompositions exist.
