Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 495868, here are decompositions:

17 + 495851 = 495868
41 + 495827 = 495868
47 + 495821 = 495868
71 + 495797 = 495868
167 + 495701 = 495868
239 + 495629 = 495868
251 + 495617 = 495868
257 + 495611 = 495868

Showing the first eight; more decompositions exist.
