Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19996, here are decompositions:

3 + 19993 = 19996
5 + 19991 = 19996
17 + 19979 = 19996
23 + 19973 = 19996
47 + 19949 = 19996
59 + 19937 = 19996
83 + 19913 = 19996
107 + 19889 = 19996

Showing the first eight; more decompositions exist.
