Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 495488, here are decompositions:

31 + 495457 = 495488
67 + 495421 = 495488
127 + 495361 = 495488
151 + 495337 = 495488
181 + 495307 = 495488
199 + 495289 = 495488
211 + 495277 = 495488
277 + 495211 = 495488

Showing the first eight; more decompositions exist.
