Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 519988, here are decompositions:

17 + 519971 = 519988
41 + 519947 = 519988
71 + 519917 = 519988
107 + 519881 = 519988
191 + 519797 = 519988
251 + 519737 = 519988
401 + 519587 = 519988
449 + 519539 = 519988

Showing the first eight; more decompositions exist.
