Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82168, here are decompositions:

5 + 82163 = 82168
29 + 82139 = 82168
101 + 82067 = 82168
131 + 82037 = 82168
137 + 82031 = 82168
197 + 81971 = 82168
239 + 81929 = 82168
269 + 81899 = 82168

Showing the first eight; more decompositions exist.
