Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670564, here are decompositions:

5 + 8670559 = 8670564
11 + 8670553 = 8670564
13 + 8670551 = 8670564
31 + 8670533 = 8670564
41 + 8670523 = 8670564
61 + 8670503 = 8670564
73 + 8670491 = 8670564
83 + 8670481 = 8670564

Showing the first eight; more decompositions exist.
