Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9160, here are decompositions:

3 + 9157 = 9160
23 + 9137 = 9160
101 + 9059 = 9160
131 + 9029 = 9160
149 + 9011 = 9160
191 + 8969 = 9160
197 + 8963 = 9160
227 + 8933 = 9160

Showing the first eight; more decompositions exist.
