Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8711128, here are decompositions:

11 + 8711117 = 8711128
47 + 8711081 = 8711128
149 + 8710979 = 8711128
281 + 8710847 = 8711128
347 + 8710781 = 8711128
401 + 8710727 = 8711128
449 + 8710679 = 8711128
479 + 8710649 = 8711128

Showing the first eight; more decompositions exist.
