Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8711668, here are decompositions:

11 + 8711657 = 8711668
41 + 8711627 = 8711668
47 + 8711621 = 8711668
107 + 8711561 = 8711668
167 + 8711501 = 8711668
179 + 8711489 = 8711668
269 + 8711399 = 8711668
281 + 8711387 = 8711668

Showing the first eight; more decompositions exist.
