Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 519828, here are decompositions:

11 + 519817 = 519828
31 + 519797 = 519828
41 + 519787 = 519828
59 + 519769 = 519828
137 + 519691 = 519828
181 + 519647 = 519828
241 + 519587 = 519828
251 + 519577 = 519828

Showing the first eight; more decompositions exist.
