Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8707930, here are decompositions:

47 + 8707883 = 8707930
53 + 8707877 = 8707930
89 + 8707841 = 8707930
113 + 8707817 = 8707930
137 + 8707793 = 8707930
149 + 8707781 = 8707930
167 + 8707763 = 8707930
233 + 8707697 = 8707930

Showing the first eight; more decompositions exist.
