Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8634564, here are decompositions:

7 + 8634557 = 8634564
13 + 8634551 = 8634564
47 + 8634517 = 8634564
61 + 8634503 = 8634564
67 + 8634497 = 8634564
83 + 8634481 = 8634564
97 + 8634467 = 8634564
137 + 8634427 = 8634564

Showing the first eight; more decompositions exist.
