Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 495864, here are decompositions:

13 + 495851 = 495864
37 + 495827 = 495864
43 + 495821 = 495864
67 + 495797 = 495864
73 + 495791 = 495864
107 + 495757 = 495864
113 + 495751 = 495864
151 + 495713 = 495864

Showing the first eight; more decompositions exist.
