Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 168160, here are decompositions:

17 + 168143 = 168160
71 + 168089 = 168160
89 + 168071 = 168160
131 + 168029 = 168160
137 + 168023 = 168160
173 + 167987 = 168160
269 + 167891 = 168160
281 + 167879 = 168160

Showing the first eight; more decompositions exist.
