Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 495572, here are decompositions:

3 + 495569 = 495572
13 + 495559 = 495572
61 + 495511 = 495572
139 + 495433 = 495572
151 + 495421 = 495572
211 + 495361 = 495572
229 + 495343 = 495572
271 + 495301 = 495572

Showing the first eight; more decompositions exist.
