Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 495222, here are decompositions:

11 + 495211 = 495222
23 + 495199 = 495222
41 + 495181 = 495222
61 + 495161 = 495222
71 + 495151 = 495222
73 + 495149 = 495222
83 + 495139 = 495222
89 + 495133 = 495222

Showing the first eight; more decompositions exist.
