Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 495918, here are decompositions:

19 + 495899 = 495918
41 + 495877 = 495918
67 + 495851 = 495918
89 + 495829 = 495918
97 + 495821 = 495918
127 + 495791 = 495918
131 + 495787 = 495918
149 + 495769 = 495918

Showing the first eight; more decompositions exist.
