Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8634664, here are decompositions:

47 + 8634617 = 8634664
83 + 8634581 = 8634664
107 + 8634557 = 8634664
113 + 8634551 = 8634664
167 + 8634497 = 8634664
197 + 8634467 = 8634664
251 + 8634413 = 8634664
281 + 8634383 = 8634664

Showing the first eight; more decompositions exist.
