Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13564, here are decompositions:
- 11 + 13553 = 13564
- 41 + 13523 = 13564
- 101 + 13463 = 13564
- 107 + 13457 = 13564
- 113 + 13451 = 13564
- 167 + 13397 = 13564
- 197 + 13367 = 13564
- 227 + 13337 = 13564
Showing the first eight; more decompositions exist.
