Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 495578, here are decompositions:

7 + 495571 = 495578
19 + 495559 = 495578
67 + 495511 = 495578
157 + 495421 = 495578
241 + 495337 = 495578
271 + 495307 = 495578
277 + 495301 = 495578
337 + 495241 = 495578

Showing the first eight; more decompositions exist.
