Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 495154, here are decompositions:

3 + 495151 = 495154
5 + 495149 = 495154
41 + 495113 = 495154
83 + 495071 = 495154
113 + 495041 = 495154
137 + 495017 = 495154
167 + 494987 = 495154
227 + 494927 = 495154

Showing the first eight; more decompositions exist.
