Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16718, here are decompositions:
- 19 + 16699 = 16718
- 61 + 16657 = 16718
- 67 + 16651 = 16718
- 151 + 16567 = 16718
- 157 + 16561 = 16718
- 199 + 16519 = 16718
- 241 + 16477 = 16718
- 271 + 16447 = 16718
Showing the first eight; more decompositions exist.
