Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 495518, here are decompositions:

7 + 495511 = 495518
61 + 495457 = 495518
97 + 495421 = 495518
157 + 495361 = 495518
181 + 495337 = 495518
211 + 495307 = 495518
229 + 495289 = 495518
241 + 495277 = 495518

Showing the first eight; more decompositions exist.
