Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82200, here are decompositions:

7 + 82193 = 82200
11 + 82189 = 82200
17 + 82183 = 82200
29 + 82171 = 82200
37 + 82163 = 82200
47 + 82153 = 82200
59 + 82141 = 82200
61 + 82139 = 82200

Showing the first eight; more decompositions exist.
