Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8711172, here are decompositions:

11 + 8711161 = 8711172
13 + 8711159 = 8711172
31 + 8711141 = 8711172
89 + 8711083 = 8711172
101 + 8711071 = 8711172
139 + 8711033 = 8711172
163 + 8711009 = 8711172
193 + 8710979 = 8711172

Showing the first eight; more decompositions exist.
