Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 519874, here are decompositions:

11 + 519863 = 519874
71 + 519803 = 519874
137 + 519737 = 519874
191 + 519683 = 519874
227 + 519647 = 519874
263 + 519611 = 519874
293 + 519581 = 519874
347 + 519527 = 519874

Showing the first eight; more decompositions exist.
