Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17540, here are decompositions:
- 31 + 17509 = 17540
- 43 + 17497 = 17540
- 73 + 17467 = 17540
- 97 + 17443 = 17540
- 109 + 17431 = 17540
- 139 + 17401 = 17540
- 151 + 17389 = 17540
- 157 + 17383 = 17540
Showing the first eight; more decompositions exist.
