Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 111158, here are decompositions:

31 + 111127 = 111158
37 + 111121 = 111158
67 + 111091 = 111158
109 + 111049 = 111158
127 + 111031 = 111158
181 + 110977 = 111158
211 + 110947 = 111158
241 + 110917 = 111158

Showing the first eight; more decompositions exist.
