Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16646, here are decompositions:

13 + 16633 = 16646
43 + 16603 = 16646
73 + 16573 = 16646
79 + 16567 = 16646
127 + 16519 = 16646
193 + 16453 = 16646
199 + 16447 = 16646
229 + 16417 = 16646

Showing the first eight; more decompositions exist.
