Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82828, here are decompositions:

17 + 82811 = 82828
29 + 82799 = 82828
41 + 82787 = 82828
47 + 82781 = 82828
71 + 82757 = 82828
101 + 82727 = 82828
107 + 82721 = 82828
227 + 82601 = 82828

Showing the first eight; more decompositions exist.
