Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8711178, here are decompositions:

17 + 8711161 = 8711178
19 + 8711159 = 8711178
37 + 8711141 = 8711178
41 + 8711137 = 8711178
61 + 8711117 = 8711178
97 + 8711081 = 8711178
107 + 8711071 = 8711178
127 + 8711051 = 8711178

Showing the first eight; more decompositions exist.
