Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9318, here are decompositions:

7 + 9311 = 9318
37 + 9281 = 9318
41 + 9277 = 9318
61 + 9257 = 9318
79 + 9239 = 9318
97 + 9221 = 9318
109 + 9209 = 9318
131 + 9187 = 9318

Showing the first eight; more decompositions exist.
