Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82220, here are decompositions:

3 + 82217 = 82220
13 + 82207 = 82220
31 + 82189 = 82220
37 + 82183 = 82220
67 + 82153 = 82220
79 + 82141 = 82220
181 + 82039 = 82220
199 + 82021 = 82220

Showing the first eight; more decompositions exist.
