Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 495912, here are decompositions:

13 + 495899 = 495912
19 + 495893 = 495912
61 + 495851 = 495912
83 + 495829 = 495912
113 + 495799 = 495912
139 + 495773 = 495912
163 + 495749 = 495912
199 + 495713 = 495912

Showing the first eight; more decompositions exist.
