Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 495384, here are decompositions:

7 + 495377 = 495384
13 + 495371 = 495384
23 + 495361 = 495384
37 + 495347 = 495384
41 + 495343 = 495384
47 + 495337 = 495384
61 + 495323 = 495384
83 + 495301 = 495384

Showing the first eight; more decompositions exist.
