Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671886, here are decompositions:

313 + 8671573 = 8671886
337 + 8671549 = 8671886
367 + 8671519 = 8671886
439 + 8671447 = 8671886
523 + 8671363 = 8671886
547 + 8671339 = 8671886
709 + 8671177 = 8671886
739 + 8671147 = 8671886

Showing the first eight; more decompositions exist.
