Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 168312, here are decompositions:

19 + 168293 = 168312
31 + 168281 = 168312
43 + 168269 = 168312
59 + 168253 = 168312
101 + 168211 = 168312
223 + 168089 = 168312
229 + 168083 = 168312
241 + 168071 = 168312

Showing the first eight; more decompositions exist.
