Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 519678, here are decompositions:

11 + 519667 = 519678
31 + 519647 = 519678
59 + 519619 = 519678
67 + 519611 = 519678
97 + 519581 = 519678
101 + 519577 = 519678
127 + 519551 = 519678
139 + 519539 = 519678

Showing the first eight; more decompositions exist.
