Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8711130, here are decompositions:

13 + 8711117 = 8711130
47 + 8711083 = 8711130
59 + 8711071 = 8711130
79 + 8711051 = 8711130
97 + 8711033 = 8711130
151 + 8710979 = 8711130
157 + 8710973 = 8711130
163 + 8710967 = 8711130

Showing the first eight; more decompositions exist.
