Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8707900, here are decompositions:

17 + 8707883 = 8707900
23 + 8707877 = 8707900
59 + 8707841 = 8707900
83 + 8707817 = 8707900
107 + 8707793 = 8707900
137 + 8707763 = 8707900
239 + 8707661 = 8707900
251 + 8707649 = 8707900

Showing the first eight; more decompositions exist.
