Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8711040, here are decompositions:

7 + 8711033 = 8711040
29 + 8711011 = 8711040
31 + 8711009 = 8711040
61 + 8710979 = 8711040
67 + 8710973 = 8711040
73 + 8710967 = 8711040
83 + 8710957 = 8711040
101 + 8710939 = 8711040

Showing the first eight; more decompositions exist.
