Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82172, here are decompositions:

19 + 82153 = 82172
31 + 82141 = 82172
43 + 82129 = 82172
151 + 82021 = 82172
163 + 82009 = 82172
199 + 81973 = 82172
229 + 81943 = 82172
241 + 81931 = 82172

Showing the first eight; more decompositions exist.
