Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82028, here are decompositions:

7 + 82021 = 82028
19 + 82009 = 82028
61 + 81967 = 82028
97 + 81931 = 82028
109 + 81919 = 82028
127 + 81901 = 82028
181 + 81847 = 82028
211 + 81817 = 82028

Showing the first eight; more decompositions exist.
