Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 495420, here are decompositions:

7 + 495413 = 495420
19 + 495401 = 495420
31 + 495389 = 495420
43 + 495377 = 495420
59 + 495361 = 495420
61 + 495359 = 495420
73 + 495347 = 495420
83 + 495337 = 495420

Showing the first eight; more decompositions exist.
