Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11566, here are decompositions:
- 17 + 11549 = 11566
- 47 + 11519 = 11566
- 83 + 11483 = 11566
- 167 + 11399 = 11566
- 173 + 11393 = 11566
- 197 + 11369 = 11566
- 293 + 11273 = 11566
- 353 + 11213 = 11566
Showing the first eight; more decompositions exist.
