Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13570, here are decompositions:
- 3 + 13567 = 13570
- 17 + 13553 = 13570
- 47 + 13523 = 13570
- 71 + 13499 = 13570
- 83 + 13487 = 13570
- 101 + 13469 = 13570
- 107 + 13463 = 13570
- 113 + 13457 = 13570
Showing the first eight; more decompositions exist.
