Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8707990, here are decompositions:

107 + 8707883 = 8707990
113 + 8707877 = 8707990
149 + 8707841 = 8707990
173 + 8707817 = 8707990
197 + 8707793 = 8707990
227 + 8707763 = 8707990
293 + 8707697 = 8707990
359 + 8707631 = 8707990

Showing the first eight; more decompositions exist.
