Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16584, here are decompositions:
- 11 + 16573 = 16584
- 17 + 16567 = 16584
- 23 + 16561 = 16584
- 31 + 16553 = 16584
- 37 + 16547 = 16584
- 97 + 16487 = 16584
- 103 + 16481 = 16584
- 107 + 16477 = 16584
Showing the first eight; more decompositions exist.
