Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 495408, here are decompositions:

7 + 495401 = 495408
19 + 495389 = 495408
31 + 495377 = 495408
37 + 495371 = 495408
47 + 495361 = 495408
61 + 495347 = 495408
71 + 495337 = 495408
101 + 495307 = 495408

Showing the first eight; more decompositions exist.
