Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 495286, here are decompositions:

17 + 495269 = 495286
137 + 495149 = 495286
167 + 495119 = 495286
173 + 495113 = 495286
269 + 495017 = 495286
347 + 494939 = 495286
353 + 494933 = 495286
359 + 494927 = 495286

Showing the first eight; more decompositions exist.
