Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 495450, here are decompositions:

13 + 495437 = 495450
17 + 495433 = 495450
29 + 495421 = 495450
37 + 495413 = 495450
61 + 495389 = 495450
73 + 495377 = 495450
79 + 495371 = 495450
89 + 495361 = 495450

Showing the first eight; more decompositions exist.
