Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 112142, here are decompositions:

3 + 112139 = 112142
13 + 112129 = 112142
31 + 112111 = 112142
73 + 112069 = 112142
193 + 111949 = 112142
223 + 111919 = 112142
229 + 111913 = 112142
271 + 111871 = 112142

Showing the first eight; more decompositions exist.
