Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671958, here are decompositions:

409 + 8671549 = 8671958
439 + 8671519 = 8671958
457 + 8671501 = 8671958
487 + 8671471 = 8671958
577 + 8671381 = 8671958
619 + 8671339 = 8671958
709 + 8671249 = 8671958
727 + 8671231 = 8671958

Showing the first eight; more decompositions exist.
