Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16690, here are decompositions:

17 + 16673 = 16690
29 + 16661 = 16690
41 + 16649 = 16690
59 + 16631 = 16690
71 + 16619 = 16690
83 + 16607 = 16690
137 + 16553 = 16690
197 + 16493 = 16690

Showing the first eight; more decompositions exist.
