Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 495442, here are decompositions:

5 + 495437 = 495442
29 + 495413 = 495442
41 + 495401 = 495442
53 + 495389 = 495442
71 + 495371 = 495442
83 + 495359 = 495442
173 + 495269 = 495442
281 + 495161 = 495442

Showing the first eight; more decompositions exist.
