Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 112812, here are decompositions:

5 + 112807 = 112812
13 + 112799 = 112812
41 + 112771 = 112812
53 + 112759 = 112812
71 + 112741 = 112812
149 + 112663 = 112812
191 + 112621 = 112812
211 + 112601 = 112812

Showing the first eight; more decompositions exist.
