Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11966, here are decompositions:

7 + 11959 = 11966
13 + 11953 = 11966
43 + 11923 = 11966
79 + 11887 = 11966
103 + 11863 = 11966
127 + 11839 = 11966
139 + 11827 = 11966
223 + 11743 = 11966

Showing the first eight; more decompositions exist.
