Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 495198, here are decompositions:

17 + 495181 = 495198
37 + 495161 = 495198
47 + 495151 = 495198
59 + 495139 = 495198
79 + 495119 = 495198
89 + 495109 = 495198
127 + 495071 = 495198
131 + 495067 = 495198

Showing the first eight; more decompositions exist.
