Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8711886, here are decompositions:

17 + 8711869 = 8711886
19 + 8711867 = 8711886
23 + 8711863 = 8711886
37 + 8711849 = 8711886
89 + 8711797 = 8711886
103 + 8711783 = 8711886
109 + 8711777 = 8711886
137 + 8711749 = 8711886

Showing the first eight; more decompositions exist.
