Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9188, here are decompositions:

7 + 9181 = 9188
31 + 9157 = 9188
37 + 9151 = 9188
61 + 9127 = 9188
79 + 9109 = 9188
97 + 9091 = 9188
139 + 9049 = 9188
181 + 9007 = 9188

Showing the first eight; more decompositions exist.
