Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8711840, here are decompositions:

19 + 8711821 = 8711840
43 + 8711797 = 8711840
73 + 8711767 = 8711840
97 + 8711743 = 8711840
103 + 8711737 = 8711840
157 + 8711683 = 8711840
223 + 8711617 = 8711840
271 + 8711569 = 8711840

Showing the first eight; more decompositions exist.
