Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 495826, here are decompositions:

5 + 495821 = 495826
29 + 495797 = 495826
53 + 495773 = 495826
113 + 495713 = 495826
179 + 495647 = 495826
197 + 495629 = 495826
239 + 495587 = 495826
257 + 495569 = 495826

Showing the first eight; more decompositions exist.
