Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8711888, here are decompositions:

19 + 8711869 = 8711888
37 + 8711851 = 8711888
67 + 8711821 = 8711888
139 + 8711749 = 8711888
151 + 8711737 = 8711888
181 + 8711707 = 8711888
271 + 8711617 = 8711888
337 + 8711551 = 8711888

Showing the first eight; more decompositions exist.
