Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 168370, here are decompositions:

17 + 168353 = 168370
23 + 168347 = 168370
47 + 168323 = 168370
89 + 168281 = 168370
101 + 168269 = 168370
107 + 168263 = 168370
173 + 168197 = 168370
227 + 168143 = 168370

Showing the first eight; more decompositions exist.
