Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19896, here are decompositions:

5 + 19891 = 19896
7 + 19889 = 19896
29 + 19867 = 19896
43 + 19853 = 19896
53 + 19843 = 19896
83 + 19813 = 19896
103 + 19793 = 19896
137 + 19759 = 19896

Showing the first eight; more decompositions exist.
