Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 111012, here are decompositions:

23 + 110989 = 111012
43 + 110969 = 111012
61 + 110951 = 111012
73 + 110939 = 111012
79 + 110933 = 111012
89 + 110923 = 111012
103 + 110909 = 111012
113 + 110899 = 111012

Showing the first eight; more decompositions exist.
