Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13558, here are decompositions:
- 5 + 13553 = 13558
- 59 + 13499 = 13558
- 71 + 13487 = 13558
- 89 + 13469 = 13558
- 101 + 13457 = 13558
- 107 + 13451 = 13558
- 137 + 13421 = 13558
- 191 + 13367 = 13558
Showing the first eight; more decompositions exist.
