Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 495190, here are decompositions:

29 + 495161 = 495190
41 + 495149 = 495190
71 + 495119 = 495190
149 + 495041 = 495190
173 + 495017 = 495190
251 + 494939 = 495190
257 + 494933 = 495190
263 + 494927 = 495190

Showing the first eight; more decompositions exist.
