Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12726, here are decompositions:

5 + 12721 = 12726
13 + 12713 = 12726
23 + 12703 = 12726
29 + 12697 = 12726
37 + 12689 = 12726
67 + 12659 = 12726
73 + 12653 = 12726
79 + 12647 = 12726

Showing the first eight; more decompositions exist.
