Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 519916, here are decompositions:

53 + 519863 = 519916
113 + 519803 = 519916
179 + 519737 = 519916
233 + 519683 = 519916
269 + 519647 = 519916
389 + 519527 = 519916
503 + 519413 = 519916
557 + 519359 = 519916

Showing the first eight; more decompositions exist.
