Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13928, here are decompositions:

7 + 13921 = 13928
97 + 13831 = 13928
139 + 13789 = 13928
199 + 13729 = 13928
241 + 13687 = 13928
331 + 13597 = 13928
337 + 13591 = 13928
487 + 13441 = 13928

Showing the first eight; more decompositions exist.
