Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 111910, here are decompositions:

17 + 111893 = 111910
41 + 111869 = 111910
47 + 111863 = 111910
53 + 111857 = 111910
83 + 111827 = 111910
89 + 111821 = 111910
131 + 111779 = 111910
137 + 111773 = 111910

Showing the first eight; more decompositions exist.
