Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8636656, here are decompositions:

23 + 8636633 = 8636656
29 + 8636627 = 8636656
53 + 8636603 = 8636656
107 + 8636549 = 8636656
113 + 8636543 = 8636656
233 + 8636423 = 8636656
269 + 8636387 = 8636656
419 + 8636237 = 8636656

Showing the first eight; more decompositions exist.
