Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 495280, here are decompositions:

3 + 495277 = 495280
11 + 495269 = 495280
59 + 495221 = 495280
131 + 495149 = 495280
167 + 495113 = 495280
239 + 495041 = 495280
263 + 495017 = 495280
293 + 494987 = 495280

Showing the first eight; more decompositions exist.
