Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 495172, here are decompositions:

11 + 495161 = 495172
23 + 495149 = 495172
53 + 495119 = 495172
59 + 495113 = 495172
101 + 495071 = 495172
131 + 495041 = 495172
233 + 494939 = 495172
239 + 494933 = 495172

Showing the first eight; more decompositions exist.
