Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 495428, here are decompositions:

7 + 495421 = 495428
67 + 495361 = 495428
127 + 495301 = 495428
139 + 495289 = 495428
151 + 495277 = 495428
229 + 495199 = 495428
277 + 495151 = 495428
691 + 494737 = 495428

Showing the first eight; more decompositions exist.
