Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8711564, here are decompositions:

3 + 8711561 = 8711564
13 + 8711551 = 8711564
31 + 8711533 = 8711564
73 + 8711491 = 8711564
97 + 8711467 = 8711564
163 + 8711401 = 8711564
181 + 8711383 = 8711564
601 + 8710963 = 8711564

Showing the first eight; more decompositions exist.
