Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19956, here are decompositions:

7 + 19949 = 19956
19 + 19937 = 19956
29 + 19927 = 19956
37 + 19919 = 19956
43 + 19913 = 19956
67 + 19889 = 19956
89 + 19867 = 19956
103 + 19853 = 19956

Showing the first eight; more decompositions exist.
