Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 519836, here are decompositions:

19 + 519817 = 519836
43 + 519793 = 519836
67 + 519769 = 519836
103 + 519733 = 519836
193 + 519643 = 519836
283 + 519553 = 519836
313 + 519523 = 519836
337 + 519499 = 519836

Showing the first eight; more decompositions exist.
