Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670556, here are decompositions:

3 + 8670553 = 8670556
5 + 8670551 = 8670556
23 + 8670533 = 8670556
47 + 8670509 = 8670556
53 + 8670503 = 8670556
149 + 8670407 = 8670556
317 + 8670239 = 8670556
359 + 8670197 = 8670556

Showing the first eight; more decompositions exist.
