Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 168172, here are decompositions:

29 + 168143 = 168172
83 + 168089 = 168172
89 + 168083 = 168172
101 + 168071 = 168172
149 + 168023 = 168172
281 + 167891 = 168172
293 + 167879 = 168172
311 + 167861 = 168172

Showing the first eight; more decompositions exist.
