Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 111916, here are decompositions:

3 + 111913 = 111916
23 + 111893 = 111916
47 + 111869 = 111916
53 + 111863 = 111916
59 + 111857 = 111916
83 + 111833 = 111916
89 + 111827 = 111916
137 + 111779 = 111916

Showing the first eight; more decompositions exist.
