Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 111960, here are decompositions:

7 + 111953 = 111960
11 + 111949 = 111960
41 + 111919 = 111960
47 + 111913 = 111960
67 + 111893 = 111960
89 + 111871 = 111960
97 + 111863 = 111960
103 + 111857 = 111960

Showing the first eight; more decompositions exist.
