Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 168162, here are decompositions:

11 + 168151 = 168162
19 + 168143 = 168162
53 + 168109 = 168162
73 + 168089 = 168162
79 + 168083 = 168162
139 + 168023 = 168162
149 + 168013 = 168162
191 + 167971 = 168162

Showing the first eight; more decompositions exist.
