Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671028, here are decompositions:

19 + 8671009 = 8671028
31 + 8670997 = 8671028
109 + 8670919 = 8671028
277 + 8670751 = 8671028
349 + 8670679 = 8671028
409 + 8670619 = 8671028
439 + 8670589 = 8671028
547 + 8670481 = 8671028

Showing the first eight; more decompositions exist.
