Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8707860, here are decompositions:

17 + 8707843 = 8707860
19 + 8707841 = 8707860
23 + 8707837 = 8707860
43 + 8707817 = 8707860
67 + 8707793 = 8707860
79 + 8707781 = 8707860
97 + 8707763 = 8707860
107 + 8707753 = 8707860

Showing the first eight; more decompositions exist.
