Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 495812, here are decompositions:

13 + 495799 = 495812
43 + 495769 = 495812
61 + 495751 = 495812
193 + 495619 = 495812
199 + 495613 = 495812
223 + 495589 = 495812
241 + 495571 = 495812
379 + 495433 = 495812

Showing the first eight; more decompositions exist.
