Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 111018, here are decompositions:

29 + 110989 = 111018
41 + 110977 = 111018
67 + 110951 = 111018
71 + 110947 = 111018
79 + 110939 = 111018
97 + 110921 = 111018
101 + 110917 = 111018
109 + 110909 = 111018

Showing the first eight; more decompositions exist.
