Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82170, here are decompositions:

7 + 82163 = 82170
17 + 82153 = 82170
29 + 82141 = 82170
31 + 82139 = 82170
41 + 82129 = 82170
97 + 82073 = 82170
103 + 82067 = 82170
131 + 82039 = 82170

Showing the first eight; more decompositions exist.
