Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 519538, here are decompositions:

11 + 519527 = 519538
17 + 519521 = 519538
29 + 519509 = 519538
167 + 519371 = 519538
179 + 519359 = 519538
251 + 519287 = 519538
269 + 519269 = 519538
281 + 519257 = 519538

Showing the first eight; more decompositions exist.
