Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8636664, here are decompositions:

17 + 8636647 = 8636664
31 + 8636633 = 8636664
37 + 8636627 = 8636664
61 + 8636603 = 8636664
73 + 8636591 = 8636664
83 + 8636581 = 8636664
131 + 8636533 = 8636664
151 + 8636513 = 8636664

Showing the first eight; more decompositions exist.
