Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 519978, here are decompositions:

7 + 519971 = 519978
31 + 519947 = 519978
47 + 519931 = 519978
59 + 519919 = 519978
61 + 519917 = 519978
71 + 519907 = 519978
89 + 519889 = 519978
97 + 519881 = 519978

Showing the first eight; more decompositions exist.
