Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 111220, here are decompositions:

3 + 111217 = 111220
29 + 111191 = 111220
71 + 111149 = 111220
101 + 111119 = 111220
167 + 111053 = 111220
191 + 111029 = 111220
251 + 110969 = 111220
269 + 110951 = 111220

Showing the first eight; more decompositions exist.
