Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490566, here are decompositions:

7 + 490559 = 490566
17 + 490549 = 490566
23 + 490543 = 490566
29 + 490537 = 490566
47 + 490519 = 490566
67 + 490499 = 490566
73 + 490493 = 490566
103 + 490463 = 490566

Showing the first eight; more decompositions exist.
