Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 168144, here are decompositions:

17 + 168127 = 168144
61 + 168083 = 168144
73 + 168071 = 168144
101 + 168043 = 168144
107 + 168037 = 168144
131 + 168013 = 168144
157 + 167987 = 168144
173 + 167971 = 168144

Showing the first eight; more decompositions exist.
