Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 168170, here are decompositions:

19 + 168151 = 168170
43 + 168127 = 168170
61 + 168109 = 168170
103 + 168067 = 168170
127 + 168043 = 168170
157 + 168013 = 168170
199 + 167971 = 168170
271 + 167899 = 168170

Showing the first eight; more decompositions exist.
