Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 519516, here are decompositions:

7 + 519509 = 519516
17 + 519499 = 519516
29 + 519487 = 519516
59 + 519457 = 519516
83 + 519433 = 519516
89 + 519427 = 519516
103 + 519413 = 519516
157 + 519359 = 519516

Showing the first eight; more decompositions exist.
