Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 495178, here are decompositions:

17 + 495161 = 495178
29 + 495149 = 495178
59 + 495119 = 495178
107 + 495071 = 495178
137 + 495041 = 495178
191 + 494987 = 495178
239 + 494939 = 495178
251 + 494927 = 495178

Showing the first eight; more decompositions exist.
