Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 189178, here are decompositions:

29 + 189149 = 189178
137 + 189041 = 189178
167 + 189011 = 189178
179 + 188999 = 189178
239 + 188939 = 189178
251 + 188927 = 189178
317 + 188861 = 189178
347 + 188831 = 189178

Showing the first eight; more decompositions exist.
