Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13566, here are decompositions:
- 13 + 13553 = 13566
- 29 + 13537 = 13566
- 43 + 13523 = 13566
- 53 + 13513 = 13566
- 67 + 13499 = 13566
- 79 + 13487 = 13566
- 89 + 13477 = 13566
- 97 + 13469 = 13566
Showing the first eight; more decompositions exist.
