Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 519990, here are decompositions:

19 + 519971 = 519990
43 + 519947 = 519990
47 + 519943 = 519990
59 + 519931 = 519990
67 + 519923 = 519990
71 + 519919 = 519990
73 + 519917 = 519990
83 + 519907 = 519990

Showing the first eight; more decompositions exist.
