Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 495728, here are decompositions:

61 + 495667 = 495728
109 + 495619 = 495728
139 + 495589 = 495728
157 + 495571 = 495728
271 + 495457 = 495728
307 + 495421 = 495728
367 + 495361 = 495728
421 + 495307 = 495728

Showing the first eight; more decompositions exist.
