Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 495778, here are decompositions:

5 + 495773 = 495778
29 + 495749 = 495778
71 + 495707 = 495778
131 + 495647 = 495778
149 + 495629 = 495778
167 + 495611 = 495778
191 + 495587 = 495778
251 + 495527 = 495778

Showing the first eight; more decompositions exist.
