Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17128, here are decompositions:

5 + 17123 = 17128
11 + 17117 = 17128
29 + 17099 = 17128
101 + 17027 = 17128
107 + 17021 = 17128
149 + 16979 = 17128
191 + 16937 = 17128
197 + 16931 = 17128

Showing the first eight; more decompositions exist.
