Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 495658, here are decompositions:

11 + 495647 = 495658
29 + 495629 = 495658
41 + 495617 = 495658
47 + 495611 = 495658
71 + 495587 = 495658
89 + 495569 = 495658
101 + 495557 = 495658
131 + 495527 = 495658

Showing the first eight; more decompositions exist.
