Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 111200, here are decompositions:

13 + 111187 = 111200
73 + 111127 = 111200
79 + 111121 = 111200
97 + 111103 = 111200
109 + 111091 = 111200
151 + 111049 = 111200
157 + 111043 = 111200
211 + 110989 = 111200

Showing the first eight; more decompositions exist.
