Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9124, here are decompositions:

83 + 9041 = 9124
113 + 9011 = 9124
173 + 8951 = 9124
191 + 8933 = 9124
257 + 8867 = 9124
263 + 8861 = 9124
293 + 8831 = 9124
317 + 8807 = 9124

Showing the first eight; more decompositions exist.
