Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 495742, here are decompositions:

29 + 495713 = 495742
41 + 495701 = 495742
113 + 495629 = 495742
131 + 495611 = 495742
173 + 495569 = 495742
179 + 495563 = 495742
251 + 495491 = 495742
281 + 495461 = 495742

Showing the first eight; more decompositions exist.
