Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8711140, here are decompositions:

3 + 8711137 = 8711140
23 + 8711117 = 8711140
59 + 8711081 = 8711140
89 + 8711051 = 8711140
107 + 8711033 = 8711140
131 + 8711009 = 8711140
167 + 8710973 = 8711140
173 + 8710967 = 8711140

Showing the first eight; more decompositions exist.
