Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9280, here are decompositions:

3 + 9277 = 9280
23 + 9257 = 9280
41 + 9239 = 9280
53 + 9227 = 9280
59 + 9221 = 9280
71 + 9209 = 9280
107 + 9173 = 9280
239 + 9041 = 9280

Showing the first eight; more decompositions exist.
