Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17428, here are decompositions:
- 11 + 17417 = 17428
- 41 + 17387 = 17428
- 101 + 17327 = 17428
- 107 + 17321 = 17428
- 137 + 17291 = 17428
- 197 + 17231 = 17428
- 239 + 17189 = 17428
- 269 + 17159 = 17428
Showing the first eight; more decompositions exist.
