Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166162, here are decompositions:

5 + 166157 = 166162
11 + 166151 = 166162
131 + 166031 = 166162
149 + 166013 = 166162
179 + 165983 = 166162
383 + 165779 = 166162
443 + 165719 = 166162
449 + 165713 = 166162

Showing the first eight; more decompositions exist.
