Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 495228, here are decompositions:

7 + 495221 = 495228
17 + 495211 = 495228
29 + 495199 = 495228
47 + 495181 = 495228
67 + 495161 = 495228
79 + 495149 = 495228
89 + 495139 = 495228
109 + 495119 = 495228

Showing the first eight; more decompositions exist.
