Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9220, here are decompositions:

11 + 9209 = 9220
17 + 9203 = 9220
47 + 9173 = 9220
59 + 9161 = 9220
83 + 9137 = 9220
179 + 9041 = 9220
191 + 9029 = 9220
251 + 8969 = 9220

Showing the first eight; more decompositions exist.
