Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16988, here are decompositions:

7 + 16981 = 16988
61 + 16927 = 16988
67 + 16921 = 16988
109 + 16879 = 16988
157 + 16831 = 16988
229 + 16759 = 16988
241 + 16747 = 16988
331 + 16657 = 16988

Showing the first eight; more decompositions exist.
