Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 165882, here are decompositions:

5 + 165877 = 165882
53 + 165829 = 165882
71 + 165811 = 165882
83 + 165799 = 165882
103 + 165779 = 165882
163 + 165719 = 165882
173 + 165709 = 165882
179 + 165703 = 165882

Showing the first eight; more decompositions exist.
