Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8711856, here are decompositions:

5 + 8711851 = 8711856
7 + 8711849 = 8711856
59 + 8711797 = 8711856
73 + 8711783 = 8711856
79 + 8711777 = 8711856
89 + 8711767 = 8711856
107 + 8711749 = 8711856
113 + 8711743 = 8711856

Showing the first eight; more decompositions exist.
