Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 495730, here are decompositions:

17 + 495713 = 495730
23 + 495707 = 495730
29 + 495701 = 495730
83 + 495647 = 495730
101 + 495629 = 495730
113 + 495617 = 495730
167 + 495563 = 495730
173 + 495557 = 495730

Showing the first eight; more decompositions exist.
