Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8707888, here are decompositions:

5 + 8707883 = 8707888
11 + 8707877 = 8707888
47 + 8707841 = 8707888
71 + 8707817 = 8707888
107 + 8707781 = 8707888
191 + 8707697 = 8707888
227 + 8707661 = 8707888
239 + 8707649 = 8707888

Showing the first eight; more decompositions exist.
