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.
