Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 495186, here are decompositions:

5 + 495181 = 495186
37 + 495149 = 495186
47 + 495139 = 495186
53 + 495133 = 495186
67 + 495119 = 495186
73 + 495113 = 495186
149 + 495037 = 495186
199 + 494987 = 495186

Showing the first eight; more decompositions exist.
