Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 111168, here are decompositions:

19 + 111149 = 111168
41 + 111127 = 111168
47 + 111121 = 111168
59 + 111109 = 111168
137 + 111031 = 111168
139 + 111029 = 111168
179 + 110989 = 111168
191 + 110977 = 111168

Showing the first eight; more decompositions exist.
