Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 519630, here are decompositions:

11 + 519619 = 519630
19 + 519611 = 519630
43 + 519587 = 519630
53 + 519577 = 519630
79 + 519551 = 519630
103 + 519527 = 519630
107 + 519523 = 519630
109 + 519521 = 519630

Showing the first eight; more decompositions exist.
