Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 111442, here are decompositions:

3 + 111439 = 111442
11 + 111431 = 111442
101 + 111341 = 111442
173 + 111269 = 111442
179 + 111263 = 111442
251 + 111191 = 111442
293 + 111149 = 111442
389 + 111053 = 111442

Showing the first eight; more decompositions exist.
