Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 168080, here are decompositions:

13 + 168067 = 168080
37 + 168043 = 168080
43 + 168037 = 168080
67 + 168013 = 168080
109 + 167971 = 168080
127 + 167953 = 168080
163 + 167917 = 168080
181 + 167899 = 168080

Showing the first eight; more decompositions exist.
