Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 495570, here are decompositions:

7 + 495563 = 495570
11 + 495559 = 495570
13 + 495557 = 495570
43 + 495527 = 495570
59 + 495511 = 495570
79 + 495491 = 495570
109 + 495461 = 495570
113 + 495457 = 495570

Showing the first eight; more decompositions exist.
