Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 112428, here are decompositions:

31 + 112397 = 112428
67 + 112361 = 112428
79 + 112349 = 112428
89 + 112339 = 112428
97 + 112331 = 112428
101 + 112327 = 112428
131 + 112297 = 112428
137 + 112291 = 112428

Showing the first eight; more decompositions exist.
