Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8711028, here are decompositions:

17 + 8711011 = 8711028
19 + 8711009 = 8711028
61 + 8710967 = 8711028
71 + 8710957 = 8711028
89 + 8710939 = 8711028
181 + 8710847 = 8711028
199 + 8710829 = 8711028
257 + 8710771 = 8711028

Showing the first eight; more decompositions exist.
