Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 519618, here are decompositions:

7 + 519611 = 519618
31 + 519587 = 519618
37 + 519581 = 519618
41 + 519577 = 519618
67 + 519551 = 519618
79 + 519539 = 519618
97 + 519521 = 519618
109 + 519509 = 519618

Showing the first eight; more decompositions exist.
