Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 519938, here are decompositions:

7 + 519931 = 519938
19 + 519919 = 519938
31 + 519907 = 519938
151 + 519787 = 519938
271 + 519667 = 519938
439 + 519499 = 519938
547 + 519391 = 519938
631 + 519307 = 519938

Showing the first eight; more decompositions exist.
