Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8711190, here are decompositions:

11 + 8711179 = 8711190
29 + 8711161 = 8711190
31 + 8711159 = 8711190
53 + 8711137 = 8711190
73 + 8711117 = 8711190
107 + 8711083 = 8711190
109 + 8711081 = 8711190
139 + 8711051 = 8711190

Showing the first eight; more decompositions exist.
