Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16606, here are decompositions:

3 + 16603 = 16606
53 + 16553 = 16606
59 + 16547 = 16606
113 + 16493 = 16606
173 + 16433 = 16606
179 + 16427 = 16606
257 + 16349 = 16606
353 + 16253 = 16606

Showing the first eight; more decompositions exist.
