Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8711558, here are decompositions:

7 + 8711551 = 8711558
67 + 8711491 = 8711558
157 + 8711401 = 8711558
181 + 8711377 = 8711558
199 + 8711359 = 8711558
211 + 8711347 = 8711558
379 + 8711179 = 8711558
397 + 8711161 = 8711558

Showing the first eight; more decompositions exist.
