Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82158, here are decompositions:

5 + 82153 = 82158
17 + 82141 = 82158
19 + 82139 = 82158
29 + 82129 = 82158
107 + 82051 = 82158
127 + 82031 = 82158
137 + 82021 = 82158
149 + 82009 = 82158

Showing the first eight; more decompositions exist.
