Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 495130, here are decompositions:

11 + 495119 = 495130
17 + 495113 = 495130
59 + 495071 = 495130
89 + 495041 = 495130
113 + 495017 = 495130
191 + 494939 = 495130
197 + 494933 = 495130
227 + 494903 = 495130

Showing the first eight; more decompositions exist.
