Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671928, here are decompositions:

379 + 8671549 = 8671928
409 + 8671519 = 8671928
457 + 8671471 = 8671928
487 + 8671441 = 8671928
547 + 8671381 = 8671928
607 + 8671321 = 8671928
709 + 8671219 = 8671928
751 + 8671177 = 8671928

Showing the first eight; more decompositions exist.
