Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 495100, here are decompositions:

29 + 495071 = 495100
59 + 495041 = 495100
83 + 495017 = 495100
113 + 494987 = 495100
167 + 494933 = 495100
173 + 494927 = 495100
197 + 494903 = 495100
227 + 494873 = 495100

Showing the first eight; more decompositions exist.
