Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671182, here are decompositions:

5 + 8671177 = 8671182
31 + 8671151 = 8671182
83 + 8671099 = 8671182
131 + 8671051 = 8671182
151 + 8671031 = 8671182
173 + 8671009 = 8671182
193 + 8670989 = 8671182
239 + 8670943 = 8671182

Showing the first eight; more decompositions exist.
