Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8711858, here are decompositions:

7 + 8711851 = 8711858
37 + 8711821 = 8711858
61 + 8711797 = 8711858
109 + 8711749 = 8711858
139 + 8711719 = 8711858
151 + 8711707 = 8711858
241 + 8711617 = 8711858
307 + 8711551 = 8711858

Showing the first eight; more decompositions exist.
