Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8711838, here are decompositions:

17 + 8711821 = 8711838
41 + 8711797 = 8711838
61 + 8711777 = 8711838
71 + 8711767 = 8711838
89 + 8711749 = 8711838
97 + 8711741 = 8711838
101 + 8711737 = 8711838
131 + 8711707 = 8711838

Showing the first eight; more decompositions exist.
