Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12966, here are decompositions:

7 + 12959 = 12966
13 + 12953 = 12966
43 + 12923 = 12966
47 + 12919 = 12966
59 + 12907 = 12966
67 + 12899 = 12966
73 + 12893 = 12966
113 + 12853 = 12966

Showing the first eight; more decompositions exist.
