Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3568, here are decompositions:
- 11 + 3557 = 3568
- 29 + 3539 = 3568
- 41 + 3527 = 3568
- 101 + 3467 = 3568
- 107 + 3461 = 3568
- 179 + 3389 = 3568
- 197 + 3371 = 3568
- 239 + 3329 = 3568
Showing the first eight; more decompositions exist.
