Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 495886, here are decompositions:

59 + 495827 = 495886
89 + 495797 = 495886
113 + 495773 = 495886
137 + 495749 = 495886
173 + 495713 = 495886
179 + 495707 = 495886
239 + 495647 = 495886
257 + 495629 = 495886

Showing the first eight; more decompositions exist.
