Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 111100, here are decompositions:

47 + 111053 = 111100
71 + 111029 = 111100
131 + 110969 = 111100
149 + 110951 = 111100
167 + 110933 = 111100
173 + 110927 = 111100
179 + 110921 = 111100
191 + 110909 = 111100

Showing the first eight; more decompositions exist.
