Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8711868, here are decompositions:

5 + 8711863 = 8711868
17 + 8711851 = 8711868
19 + 8711849 = 8711868
47 + 8711821 = 8711868
71 + 8711797 = 8711868
101 + 8711767 = 8711868
127 + 8711741 = 8711868
131 + 8711737 = 8711868

Showing the first eight; more decompositions exist.
