Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 495738, here are decompositions:

31 + 495707 = 495738
37 + 495701 = 495738
59 + 495679 = 495738
71 + 495667 = 495738
101 + 495637 = 495738
109 + 495629 = 495738
127 + 495611 = 495738
149 + 495589 = 495738

Showing the first eight; more decompositions exist.
