Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671086, here are decompositions:

19 + 8671067 = 8671086
23 + 8671063 = 8671086
29 + 8671057 = 8671086
79 + 8671007 = 8671086
89 + 8670997 = 8671086
97 + 8670989 = 8671086
139 + 8670947 = 8671086
167 + 8670919 = 8671086

Showing the first eight; more decompositions exist.
