Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 111306, here are decompositions:

5 + 111301 = 111306
37 + 111269 = 111306
43 + 111263 = 111306
53 + 111253 = 111306
79 + 111227 = 111306
89 + 111217 = 111306
157 + 111149 = 111306
163 + 111143 = 111306

Showing the first eight; more decompositions exist.
