Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17512, here are decompositions:
- 3 + 17509 = 17512
- 23 + 17489 = 17512
- 29 + 17483 = 17512
- 41 + 17471 = 17512
- 179 + 17333 = 17512
- 191 + 17321 = 17512
- 281 + 17231 = 17512
- 353 + 17159 = 17512
Showing the first eight; more decompositions exist.
