Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 495166, here are decompositions:

5 + 495161 = 495166
17 + 495149 = 495166
47 + 495119 = 495166
53 + 495113 = 495166
149 + 495017 = 495166
179 + 494987 = 495166
227 + 494939 = 495166
233 + 494933 = 495166

Showing the first eight; more decompositions exist.
