Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9158, here are decompositions:

7 + 9151 = 9158
31 + 9127 = 9158
67 + 9091 = 9158
109 + 9049 = 9158
151 + 9007 = 9158
157 + 9001 = 9158
229 + 8929 = 9158
271 + 8887 = 9158

Showing the first eight; more decompositions exist.
