Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188170, here are decompositions:

11 + 188159 = 188170
23 + 188147 = 188170
149 + 188021 = 188170
197 + 187973 = 188170
239 + 187931 = 188170
263 + 187907 = 188170
293 + 187877 = 188170
347 + 187823 = 188170

Showing the first eight; more decompositions exist.
