Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 112538, here are decompositions:

31 + 112507 = 112538
37 + 112501 = 112538
79 + 112459 = 112538
109 + 112429 = 112538
199 + 112339 = 112538
211 + 112327 = 112538
241 + 112297 = 112538
277 + 112261 = 112538

Showing the first eight; more decompositions exist.
