Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671586, here are decompositions:

3 + 8671583 = 8671586
13 + 8671573 = 8671586
37 + 8671549 = 8671586
67 + 8671519 = 8671586
139 + 8671447 = 8671586
193 + 8671393 = 8671586
223 + 8671363 = 8671586
337 + 8671249 = 8671586

Showing the first eight; more decompositions exist.
