Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 519816, here are decompositions:

13 + 519803 = 519816
19 + 519797 = 519816
23 + 519793 = 519816
29 + 519787 = 519816
47 + 519769 = 519816
79 + 519737 = 519816
83 + 519733 = 519816
103 + 519713 = 519816

Showing the first eight; more decompositions exist.
