Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19960, here are decompositions:

11 + 19949 = 19960
23 + 19937 = 19960
41 + 19919 = 19960
47 + 19913 = 19960
71 + 19889 = 19960
107 + 19853 = 19960
167 + 19793 = 19960
197 + 19763 = 19960

Showing the first eight; more decompositions exist.
