Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 495646, here are decompositions:

17 + 495629 = 495646
29 + 495617 = 495646
59 + 495587 = 495646
83 + 495563 = 495646
89 + 495557 = 495646
197 + 495449 = 495646
233 + 495413 = 495646
257 + 495389 = 495646

Showing the first eight; more decompositions exist.
