Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13886, here are decompositions:

3 + 13883 = 13886
7 + 13879 = 13886
13 + 13873 = 13886
79 + 13807 = 13886
97 + 13789 = 13886
127 + 13759 = 13886
157 + 13729 = 13886
163 + 13723 = 13886

Showing the first eight; more decompositions exist.
