Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 111378, here are decompositions:

5 + 111373 = 111378
31 + 111347 = 111378
37 + 111341 = 111378
41 + 111337 = 111378
61 + 111317 = 111378
107 + 111271 = 111378
109 + 111269 = 111378
149 + 111229 = 111378

Showing the first eight; more decompositions exist.
