Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 495480, here are decompositions:

19 + 495461 = 495480
23 + 495457 = 495480
31 + 495449 = 495480
43 + 495437 = 495480
47 + 495433 = 495480
59 + 495421 = 495480
67 + 495413 = 495480
79 + 495401 = 495480

Showing the first eight; more decompositions exist.
