Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 495386, here are decompositions:

43 + 495343 = 495386
79 + 495307 = 495386
97 + 495289 = 495386
109 + 495277 = 495386
277 + 495109 = 495386
349 + 495037 = 495386
487 + 494899 = 495386
643 + 494743 = 495386

Showing the first eight; more decompositions exist.
