Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11560, here are decompositions:
- 11 + 11549 = 11560
- 41 + 11519 = 11560
- 71 + 11489 = 11560
- 89 + 11471 = 11560
- 113 + 11447 = 11560
- 137 + 11423 = 11560
- 149 + 11411 = 11560
- 167 + 11393 = 11560
Showing the first eight; more decompositions exist.
