Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518758, here are decompositions:

11 + 518747 = 518758
17 + 518741 = 518758
29 + 518729 = 518758
41 + 518717 = 518758
59 + 518699 = 518758
101 + 518657 = 518758
137 + 518621 = 518758
179 + 518579 = 518758

Showing the first eight; more decompositions exist.
