Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 495644, here are decompositions:

7 + 495637 = 495644
31 + 495613 = 495644
73 + 495571 = 495644
211 + 495433 = 495644
223 + 495421 = 495644
283 + 495361 = 495644
307 + 495337 = 495644
337 + 495307 = 495644

Showing the first eight; more decompositions exist.
