Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 495638, here are decompositions:

19 + 495619 = 495638
67 + 495571 = 495638
79 + 495559 = 495638
127 + 495511 = 495638
181 + 495457 = 495638
277 + 495361 = 495638
331 + 495307 = 495638
337 + 495301 = 495638

Showing the first eight; more decompositions exist.
