Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8711644, here are decompositions:

17 + 8711627 = 8711644
23 + 8711621 = 8711644
41 + 8711603 = 8711644
83 + 8711561 = 8711644
101 + 8711543 = 8711644
197 + 8711447 = 8711644
257 + 8711387 = 8711644
281 + 8711363 = 8711644

Showing the first eight; more decompositions exist.
