Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621636, here are decompositions:

13 + 8621623 = 8621636
19 + 8621617 = 8621636
157 + 8621479 = 8621636
193 + 8621443 = 8621636
223 + 8621413 = 8621636
337 + 8621299 = 8621636
547 + 8621089 = 8621636
619 + 8621017 = 8621636

Showing the first eight; more decompositions exist.
