Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13788, here are decompositions:

7 + 13781 = 13788
29 + 13759 = 13788
31 + 13757 = 13788
37 + 13751 = 13788
59 + 13729 = 13788
67 + 13721 = 13788
79 + 13709 = 13788
97 + 13691 = 13788

Showing the first eight; more decompositions exist.
