Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9178, here are decompositions:

5 + 9173 = 9178
17 + 9161 = 9178
41 + 9137 = 9178
137 + 9041 = 9178
149 + 9029 = 9178
167 + 9011 = 9178
179 + 8999 = 9178
227 + 8951 = 9178

Showing the first eight; more decompositions exist.
