Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171168, here are decompositions:

5 + 171163 = 171168
7 + 171161 = 171168
37 + 171131 = 171168
89 + 171079 = 171168
139 + 171029 = 171168
197 + 170971 = 171168
211 + 170957 = 171168
241 + 170927 = 171168

Showing the first eight; more decompositions exist.
