Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 111072, here are decompositions:

19 + 111053 = 111072
23 + 111049 = 111072
29 + 111043 = 111072
41 + 111031 = 111072
43 + 111029 = 111072
83 + 110989 = 111072
103 + 110969 = 111072
139 + 110933 = 111072

Showing the first eight; more decompositions exist.
