Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12896, here are decompositions:

3 + 12893 = 12896
7 + 12889 = 12896
43 + 12853 = 12896
67 + 12829 = 12896
73 + 12823 = 12896
97 + 12799 = 12896
139 + 12757 = 12896
157 + 12739 = 12896

Showing the first eight; more decompositions exist.
