Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8636628, here are decompositions:

29 + 8636599 = 8636628
37 + 8636591 = 8636628
41 + 8636587 = 8636628
47 + 8636581 = 8636628
79 + 8636549 = 8636628
89 + 8636539 = 8636628
107 + 8636521 = 8636628
137 + 8636491 = 8636628

Showing the first eight; more decompositions exist.
