Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 112642, here are decompositions:

41 + 112601 = 112642
53 + 112589 = 112642
59 + 112583 = 112642
71 + 112571 = 112642
83 + 112559 = 112642
239 + 112403 = 112642
281 + 112361 = 112642
293 + 112349 = 112642

Showing the first eight; more decompositions exist.
