Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8711880, here are decompositions:

11 + 8711869 = 8711880
13 + 8711867 = 8711880
17 + 8711863 = 8711880
29 + 8711851 = 8711880
31 + 8711849 = 8711880
59 + 8711821 = 8711880
83 + 8711797 = 8711880
97 + 8711783 = 8711880

Showing the first eight; more decompositions exist.
