Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16904, here are decompositions:
- 3 + 16901 = 16904
- 61 + 16843 = 16904
- 73 + 16831 = 16904
- 157 + 16747 = 16904
- 163 + 16741 = 16904
- 211 + 16693 = 16904
- 271 + 16633 = 16904
- 331 + 16573 = 16904
Showing the first eight; more decompositions exist.
