Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8636634, here are decompositions:

7 + 8636627 = 8636634
31 + 8636603 = 8636634
43 + 8636591 = 8636634
47 + 8636587 = 8636634
53 + 8636581 = 8636634
101 + 8636533 = 8636634
113 + 8636521 = 8636634
211 + 8636423 = 8636634

Showing the first eight; more decompositions exist.
