Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9278, here are decompositions:

37 + 9241 = 9278
79 + 9199 = 9278
97 + 9181 = 9278
127 + 9151 = 9278
151 + 9127 = 9278
211 + 9067 = 9278
229 + 9049 = 9278
271 + 9007 = 9278

Showing the first eight; more decompositions exist.
