Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8653664, here are decompositions:

7 + 8653657 = 8653664
13 + 8653651 = 8653664
37 + 8653627 = 8653664
73 + 8653591 = 8653664
127 + 8653537 = 8653664
211 + 8653453 = 8653664
337 + 8653327 = 8653664
367 + 8653297 = 8653664

Showing the first eight; more decompositions exist.
