Goldbach decomposition

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.
