Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82162, here are decompositions:

23 + 82139 = 82162
89 + 82073 = 82162
131 + 82031 = 82162
149 + 82013 = 82162
191 + 81971 = 82162
233 + 81929 = 82162
263 + 81899 = 82162
293 + 81869 = 82162

Showing the first eight; more decompositions exist.
