Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12756, here are decompositions:

13 + 12743 = 12756
17 + 12739 = 12756
43 + 12713 = 12756
53 + 12703 = 12756
59 + 12697 = 12756
67 + 12689 = 12756
97 + 12659 = 12756
103 + 12653 = 12756

Showing the first eight; more decompositions exist.
