Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 519898, here are decompositions:

17 + 519881 = 519898
101 + 519797 = 519898
251 + 519647 = 519898
311 + 519587 = 519898
317 + 519581 = 519898
347 + 519551 = 519898
359 + 519539 = 519898
389 + 519509 = 519898

Showing the first eight; more decompositions exist.
