Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8707872, here are decompositions:

11 + 8707861 = 8707872
29 + 8707843 = 8707872
31 + 8707841 = 8707872
79 + 8707793 = 8707872
109 + 8707763 = 8707872
211 + 8707661 = 8707872
223 + 8707649 = 8707872
241 + 8707631 = 8707872

Showing the first eight; more decompositions exist.
