Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8711538, here are decompositions:

5 + 8711533 = 8711538
37 + 8711501 = 8711538
47 + 8711491 = 8711538
71 + 8711467 = 8711538
137 + 8711401 = 8711538
139 + 8711399 = 8711538
151 + 8711387 = 8711538
179 + 8711359 = 8711538

Showing the first eight; more decompositions exist.
