Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 495028, here are decompositions:

11 + 495017 = 495028
41 + 494987 = 495028
89 + 494939 = 495028
101 + 494927 = 495028
179 + 494849 = 495028
239 + 494789 = 495028
269 + 494759 = 495028
389 + 494639 = 495028

Showing the first eight; more decompositions exist.
