Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13976, here are decompositions:

13 + 13963 = 13976
43 + 13933 = 13976
73 + 13903 = 13976
97 + 13879 = 13976
103 + 13873 = 13976
283 + 13693 = 13976
307 + 13669 = 13976
349 + 13627 = 13976

Showing the first eight; more decompositions exist.
