Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8711540, here are decompositions:

7 + 8711533 = 8711540
73 + 8711467 = 8711540
139 + 8711401 = 8711540
157 + 8711383 = 8711540
163 + 8711377 = 8711540
181 + 8711359 = 8711540
193 + 8711347 = 8711540
379 + 8711161 = 8711540

Showing the first eight; more decompositions exist.
