Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 510864, here are decompositions:

17 + 510847 = 510864
37 + 510827 = 510864
41 + 510823 = 510864
47 + 510817 = 510864
61 + 510803 = 510864
71 + 510793 = 510864
97 + 510767 = 510864
113 + 510751 = 510864

Showing the first eight; more decompositions exist.
