Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 111372, here are decompositions:

31 + 111341 = 111372
71 + 111301 = 111372
101 + 111271 = 111372
103 + 111269 = 111372
109 + 111263 = 111372
181 + 111191 = 111372
223 + 111149 = 111372
229 + 111143 = 111372

Showing the first eight; more decompositions exist.
