Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 495418, here are decompositions:

5 + 495413 = 495418
17 + 495401 = 495418
29 + 495389 = 495418
41 + 495377 = 495418
47 + 495371 = 495418
59 + 495359 = 495418
71 + 495347 = 495418
149 + 495269 = 495418

Showing the first eight; more decompositions exist.
