Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518766, here are decompositions:

5 + 518761 = 518766
7 + 518759 = 518766
19 + 518747 = 518766
23 + 518743 = 518766
29 + 518737 = 518766
37 + 518729 = 518766
67 + 518699 = 518766
109 + 518657 = 518766

Showing the first eight; more decompositions exist.
