Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 189154, here are decompositions:

3 + 189151 = 189154
5 + 189149 = 189154
113 + 189041 = 189154
137 + 189017 = 189154
197 + 188957 = 189154
227 + 188927 = 189154
263 + 188891 = 189154
293 + 188861 = 189154

Showing the first eight; more decompositions exist.
