Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 91164, here are decompositions:

5 + 91159 = 91164
11 + 91153 = 91164
13 + 91151 = 91164
23 + 91141 = 91164
37 + 91127 = 91164
43 + 91121 = 91164
67 + 91097 = 91164
83 + 91081 = 91164

Showing the first eight; more decompositions exist.
