Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 495838, here are decompositions:

11 + 495827 = 495838
17 + 495821 = 495838
41 + 495797 = 495838
47 + 495791 = 495838
89 + 495749 = 495838
131 + 495707 = 495838
137 + 495701 = 495838
191 + 495647 = 495838

Showing the first eight; more decompositions exist.
