Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518826, here are decompositions:

13 + 518813 = 518826
17 + 518809 = 518826
19 + 518807 = 518826
23 + 518803 = 518826
47 + 518779 = 518826
59 + 518767 = 518826
67 + 518759 = 518826
79 + 518747 = 518826

Showing the first eight; more decompositions exist.
