Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12776, here are decompositions:

13 + 12763 = 12776
19 + 12757 = 12776
37 + 12739 = 12776
73 + 12703 = 12776
79 + 12697 = 12776
139 + 12637 = 12776
157 + 12619 = 12776
163 + 12613 = 12776

Showing the first eight; more decompositions exist.
