Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9172, here are decompositions:

11 + 9161 = 9172
113 + 9059 = 9172
131 + 9041 = 9172
173 + 8999 = 9172
239 + 8933 = 9172
311 + 8861 = 9172
353 + 8819 = 9172
389 + 8783 = 9172

Showing the first eight; more decompositions exist.
