Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19938, here are decompositions:

11 + 19927 = 19938
19 + 19919 = 19938
47 + 19891 = 19938
71 + 19867 = 19938
97 + 19841 = 19938
137 + 19801 = 19938
179 + 19759 = 19938
199 + 19739 = 19938

Showing the first eight; more decompositions exist.
