Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 189186, here are decompositions:

17 + 189169 = 189186
37 + 189149 = 189186
47 + 189139 = 189186
59 + 189127 = 189186
167 + 189019 = 189186
229 + 188957 = 189186
233 + 188953 = 189186
317 + 188869 = 189186

Showing the first eight; more decompositions exist.
