Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8711428, here are decompositions:

29 + 8711399 = 8711428
41 + 8711387 = 8711428
71 + 8711357 = 8711428
191 + 8711237 = 8711428
239 + 8711189 = 8711428
269 + 8711159 = 8711428
311 + 8711117 = 8711428
347 + 8711081 = 8711428

Showing the first eight; more decompositions exist.
