Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 111128, here are decompositions:

7 + 111121 = 111128
19 + 111109 = 111128
37 + 111091 = 111128
79 + 111049 = 111128
97 + 111031 = 111128
139 + 110989 = 111128
151 + 110977 = 111128
181 + 110947 = 111128

Showing the first eight; more decompositions exist.
