Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 495256, here are decompositions:

107 + 495149 = 495256
137 + 495119 = 495256
239 + 495017 = 495256
269 + 494987 = 495256
317 + 494939 = 495256
353 + 494903 = 495256
383 + 494873 = 495256
467 + 494789 = 495256

Showing the first eight; more decompositions exist.
