Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 495540, here are decompositions:

13 + 495527 = 495540
29 + 495511 = 495540
79 + 495461 = 495540
83 + 495457 = 495540
103 + 495437 = 495540
107 + 495433 = 495540
127 + 495413 = 495540
139 + 495401 = 495540

Showing the first eight; more decompositions exist.
