Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643104, here are decompositions:

13 + 8643091 = 8643104
157 + 8642947 = 8643104
193 + 8642911 = 8643104
241 + 8642863 = 8643104
331 + 8642773 = 8643104
523 + 8642581 = 8643104
571 + 8642533 = 8643104
823 + 8642281 = 8643104

Showing the first eight; more decompositions exist.
