Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8636648, here are decompositions:

61 + 8636587 = 8636648
67 + 8636581 = 8636648
109 + 8636539 = 8636648
127 + 8636521 = 8636648
157 + 8636491 = 8636648
199 + 8636449 = 8636648
271 + 8636377 = 8636648
379 + 8636269 = 8636648

Showing the first eight; more decompositions exist.
