Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 91308, here are decompositions:

5 + 91303 = 91308
11 + 91297 = 91308
17 + 91291 = 91308
59 + 91249 = 91308
71 + 91237 = 91308
79 + 91229 = 91308
109 + 91199 = 91308
149 + 91159 = 91308

Showing the first eight; more decompositions exist.
