Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9238, here are decompositions:

11 + 9227 = 9238
17 + 9221 = 9238
29 + 9209 = 9238
101 + 9137 = 9238
179 + 9059 = 9238
197 + 9041 = 9238
227 + 9011 = 9238
239 + 8999 = 9238

Showing the first eight; more decompositions exist.
