Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 495806, here are decompositions:

7 + 495799 = 495806
19 + 495787 = 495806
37 + 495769 = 495806
127 + 495679 = 495806
139 + 495667 = 495806
193 + 495613 = 495806
349 + 495457 = 495806
373 + 495433 = 495806

Showing the first eight; more decompositions exist.
