Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 495508, here are decompositions:

17 + 495491 = 495508
47 + 495461 = 495508
59 + 495449 = 495508
71 + 495437 = 495508
107 + 495401 = 495508
131 + 495377 = 495508
137 + 495371 = 495508
149 + 495359 = 495508

Showing the first eight; more decompositions exist.
