Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 519748, here are decompositions:

11 + 519737 = 519748
101 + 519647 = 519748
137 + 519611 = 519748
167 + 519581 = 519748
197 + 519551 = 519748
227 + 519521 = 519748
239 + 519509 = 519748
389 + 519359 = 519748

Showing the first eight; more decompositions exist.
