Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 111492, here are decompositions:

5 + 111487 = 111492
53 + 111439 = 111492
61 + 111431 = 111492
83 + 111409 = 111492
151 + 111341 = 111492
191 + 111301 = 111492
223 + 111269 = 111492
229 + 111263 = 111492

Showing the first eight; more decompositions exist.
