Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 519966, here are decompositions:

19 + 519947 = 519966
23 + 519943 = 519966
43 + 519923 = 519966
47 + 519919 = 519966
59 + 519907 = 519966
103 + 519863 = 519966
149 + 519817 = 519966
163 + 519803 = 519966

Showing the first eight; more decompositions exist.
