Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9286, here are decompositions:

3 + 9283 = 9286
5 + 9281 = 9286
29 + 9257 = 9286
47 + 9239 = 9286
59 + 9227 = 9286
83 + 9203 = 9286
113 + 9173 = 9286
149 + 9137 = 9286

Showing the first eight; more decompositions exist.
