Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 519660, here are decompositions:

13 + 519647 = 519660
17 + 519643 = 519660
41 + 519619 = 519660
73 + 519587 = 519660
79 + 519581 = 519660
83 + 519577 = 519660
107 + 519553 = 519660
109 + 519551 = 519660

Showing the first eight; more decompositions exist.
