Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 495288, here are decompositions:

11 + 495277 = 495288
19 + 495269 = 495288
47 + 495241 = 495288
67 + 495221 = 495288
89 + 495199 = 495288
107 + 495181 = 495288
127 + 495161 = 495288
137 + 495151 = 495288

Showing the first eight; more decompositions exist.
