Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 495648, here are decompositions:

11 + 495637 = 495648
19 + 495629 = 495648
29 + 495619 = 495648
31 + 495617 = 495648
37 + 495611 = 495648
59 + 495589 = 495648
61 + 495587 = 495648
79 + 495569 = 495648

Showing the first eight; more decompositions exist.
