Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671556, here are decompositions:

7 + 8671549 = 8671556
37 + 8671519 = 8671556
109 + 8671447 = 8671556
163 + 8671393 = 8671556
193 + 8671363 = 8671556
307 + 8671249 = 8671556
337 + 8671219 = 8671556
379 + 8671177 = 8671556

Showing the first eight; more decompositions exist.
