Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 111142, here are decompositions:

23 + 111119 = 111142
89 + 111053 = 111142
113 + 111029 = 111142
173 + 110969 = 111142
191 + 110951 = 111142
233 + 110909 = 111142
263 + 110879 = 111142
293 + 110849 = 111142

Showing the first eight; more decompositions exist.
