Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 91288, here are decompositions:

5 + 91283 = 91288
59 + 91229 = 91288
89 + 91199 = 91288
137 + 91151 = 91288
149 + 91139 = 91288
167 + 91121 = 91288
191 + 91097 = 91288
269 + 91019 = 91288

Showing the first eight; more decompositions exist.
