Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 516864, here are decompositions:

17 + 516847 = 516864
43 + 516821 = 516864
53 + 516811 = 516864
71 + 516793 = 516864
107 + 516757 = 516864
137 + 516727 = 516864
151 + 516713 = 516864
163 + 516701 = 516864

Showing the first eight; more decompositions exist.
