Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 495406, here are decompositions:

5 + 495401 = 495406
17 + 495389 = 495406
29 + 495377 = 495406
47 + 495359 = 495406
59 + 495347 = 495406
83 + 495323 = 495406
137 + 495269 = 495406
257 + 495149 = 495406

Showing the first eight; more decompositions exist.
