Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 495618, here are decompositions:

5 + 495613 = 495618
7 + 495611 = 495618
29 + 495589 = 495618
31 + 495587 = 495618
47 + 495571 = 495618
59 + 495559 = 495618
61 + 495557 = 495618
107 + 495511 = 495618

Showing the first eight; more decompositions exist.
