Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 495840, here are decompositions:

11 + 495829 = 495840
13 + 495827 = 495840
19 + 495821 = 495840
41 + 495799 = 495840
43 + 495797 = 495840
53 + 495787 = 495840
67 + 495773 = 495840
71 + 495769 = 495840

Showing the first eight; more decompositions exist.
