Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8711218, here are decompositions:

29 + 8711189 = 8711218
59 + 8711159 = 8711218
101 + 8711117 = 8711218
137 + 8711081 = 8711218
167 + 8711051 = 8711218
239 + 8710979 = 8711218
251 + 8710967 = 8711218
389 + 8710829 = 8711218

Showing the first eight; more decompositions exist.
