Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164168, here are decompositions:

19 + 164149 = 164168
79 + 164089 = 164168
97 + 164071 = 164168
157 + 164011 = 164168
181 + 163987 = 164168
241 + 163927 = 164168
307 + 163861 = 164168
349 + 163819 = 164168

Showing the first eight; more decompositions exist.
