Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 495250, here are decompositions:

29 + 495221 = 495250
89 + 495161 = 495250
101 + 495149 = 495250
131 + 495119 = 495250
137 + 495113 = 495250
179 + 495071 = 495250
233 + 495017 = 495250
263 + 494987 = 495250

Showing the first eight; more decompositions exist.
