Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 495272, here are decompositions:

3 + 495269 = 495272
31 + 495241 = 495272
61 + 495211 = 495272
73 + 495199 = 495272
139 + 495133 = 495272
163 + 495109 = 495272
229 + 495043 = 495272
313 + 494959 = 495272

Showing the first eight; more decompositions exist.
