Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82180, here are decompositions:

17 + 82163 = 82180
41 + 82139 = 82180
107 + 82073 = 82180
113 + 82067 = 82180
149 + 82031 = 82180
167 + 82013 = 82180
173 + 82007 = 82180
227 + 81953 = 82180

Showing the first eight; more decompositions exist.
