Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490586, here are decompositions:

7 + 490579 = 490586
13 + 490573 = 490586
37 + 490549 = 490586
43 + 490543 = 490586
67 + 490519 = 490586
127 + 490459 = 490586
193 + 490393 = 490586
277 + 490309 = 490586

Showing the first eight; more decompositions exist.
