Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 112782, here are decompositions:

11 + 112771 = 112782
23 + 112759 = 112782
41 + 112741 = 112782
139 + 112643 = 112782
179 + 112603 = 112782
181 + 112601 = 112782
193 + 112589 = 112782
199 + 112583 = 112782

Showing the first eight; more decompositions exist.
