Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 168228, here are decompositions:

17 + 168211 = 168228
31 + 168197 = 168228
101 + 168127 = 168228
139 + 168089 = 168228
157 + 168071 = 168228
191 + 168037 = 168228
199 + 168029 = 168228
241 + 167987 = 168228

Showing the first eight; more decompositions exist.
