Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 495400, here are decompositions:

11 + 495389 = 495400
23 + 495377 = 495400
29 + 495371 = 495400
41 + 495359 = 495400
53 + 495347 = 495400
131 + 495269 = 495400
179 + 495221 = 495400
239 + 495161 = 495400

Showing the first eight; more decompositions exist.
