Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 495156, here are decompositions:

5 + 495151 = 495156
7 + 495149 = 495156
17 + 495139 = 495156
23 + 495133 = 495156
37 + 495119 = 495156
43 + 495113 = 495156
47 + 495109 = 495156
89 + 495067 = 495156

Showing the first eight; more decompositions exist.
