Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 111380, here are decompositions:

7 + 111373 = 111380
43 + 111337 = 111380
79 + 111301 = 111380
109 + 111271 = 111380
127 + 111253 = 111380
151 + 111229 = 111380
163 + 111217 = 111380
193 + 111187 = 111380

Showing the first eight; more decompositions exist.
