Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8707824, here are decompositions:

7 + 8707817 = 8707824
31 + 8707793 = 8707824
43 + 8707781 = 8707824
61 + 8707763 = 8707824
71 + 8707753 = 8707824
113 + 8707711 = 8707824
127 + 8707697 = 8707824
137 + 8707687 = 8707824

Showing the first eight; more decompositions exist.
