Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8711158, here are decompositions:

17 + 8711141 = 8711158
41 + 8711117 = 8711158
107 + 8711051 = 8711158
149 + 8711009 = 8711158
179 + 8710979 = 8711158
191 + 8710967 = 8711158
311 + 8710847 = 8711158
431 + 8710727 = 8711158

Showing the first eight; more decompositions exist.
