Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 111966, here are decompositions:

7 + 111959 = 111966
13 + 111953 = 111966
17 + 111949 = 111966
47 + 111919 = 111966
53 + 111913 = 111966
73 + 111893 = 111966
97 + 111869 = 111966
103 + 111863 = 111966

Showing the first eight; more decompositions exist.
