Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16784, here are decompositions:
- 37 + 16747 = 16784
- 43 + 16741 = 16784
- 127 + 16657 = 16784
- 151 + 16633 = 16784
- 181 + 16603 = 16784
- 211 + 16573 = 16784
- 223 + 16561 = 16784
- 307 + 16477 = 16784
Showing the first eight; more decompositions exist.
