Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82020, here are decompositions:

7 + 82013 = 82020
11 + 82009 = 82020
13 + 82007 = 82020
17 + 82003 = 82020
47 + 81973 = 82020
53 + 81967 = 82020
67 + 81953 = 82020
83 + 81937 = 82020

Showing the first eight; more decompositions exist.
