Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9428, here are decompositions:

7 + 9421 = 9428
31 + 9397 = 9428
37 + 9391 = 9428
79 + 9349 = 9428
109 + 9319 = 9428
151 + 9277 = 9428
229 + 9199 = 9428
241 + 9187 = 9428

Showing the first eight; more decompositions exist.
