Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 167168, here are decompositions:

19 + 167149 = 167168
61 + 167107 = 167168
97 + 167071 = 167168
151 + 167017 = 167168
181 + 166987 = 167168
307 + 166861 = 167168
499 + 166669 = 167168
541 + 166627 = 167168

Showing the first eight; more decompositions exist.
