Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13826, here are decompositions:

19 + 13807 = 13826
37 + 13789 = 13826
67 + 13759 = 13826
97 + 13729 = 13826
103 + 13723 = 13826
139 + 13687 = 13826
157 + 13669 = 13826
193 + 13633 = 13826

Showing the first eight; more decompositions exist.
