Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 495808, here are decompositions:

11 + 495797 = 495808
17 + 495791 = 495808
59 + 495749 = 495808
101 + 495707 = 495808
107 + 495701 = 495808
179 + 495629 = 495808
191 + 495617 = 495808
197 + 495611 = 495808

Showing the first eight; more decompositions exist.
