Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 495404, here are decompositions:

3 + 495401 = 495404
43 + 495361 = 495404
61 + 495343 = 495404
67 + 495337 = 495404
97 + 495307 = 495404
103 + 495301 = 495404
127 + 495277 = 495404
163 + 495241 = 495404

Showing the first eight; more decompositions exist.
