Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16638, here are decompositions:

5 + 16633 = 16638
7 + 16631 = 16638
19 + 16619 = 16638
31 + 16607 = 16638
71 + 16567 = 16638
109 + 16529 = 16638
151 + 16487 = 16638
157 + 16481 = 16638

Showing the first eight; more decompositions exist.
