Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51828, here are decompositions:

11 + 51817 = 51828
31 + 51797 = 51828
41 + 51787 = 51828
59 + 51769 = 51828
61 + 51767 = 51828
79 + 51749 = 51828
107 + 51721 = 51828
109 + 51719 = 51828

Showing the first eight; more decompositions exist.
