Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 495820, here are decompositions:

23 + 495797 = 495820
29 + 495791 = 495820
47 + 495773 = 495820
71 + 495749 = 495820
107 + 495713 = 495820
113 + 495707 = 495820
173 + 495647 = 495820
191 + 495629 = 495820

Showing the first eight; more decompositions exist.
