Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490572, here are decompositions:

13 + 490559 = 490572
23 + 490549 = 490572
29 + 490543 = 490572
31 + 490541 = 490572
53 + 490519 = 490572
73 + 490499 = 490572
79 + 490493 = 490572
109 + 490463 = 490572

Showing the first eight; more decompositions exist.
