Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 111272, here are decompositions:

3 + 111269 = 111272
19 + 111253 = 111272
43 + 111229 = 111272
61 + 111211 = 111272
151 + 111121 = 111272
163 + 111109 = 111272
181 + 111091 = 111272
223 + 111049 = 111272

Showing the first eight; more decompositions exist.
