Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 495550, here are decompositions:

23 + 495527 = 495550
59 + 495491 = 495550
89 + 495461 = 495550
101 + 495449 = 495550
113 + 495437 = 495550
137 + 495413 = 495550
149 + 495401 = 495550
173 + 495377 = 495550

Showing the first eight; more decompositions exist.
