Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8636128, here are decompositions:

5 + 8636123 = 8636128
41 + 8636087 = 8636128
47 + 8636081 = 8636128
71 + 8636057 = 8636128
89 + 8636039 = 8636128
107 + 8636021 = 8636128
311 + 8635817 = 8636128
317 + 8635811 = 8636128

Showing the first eight; more decompositions exist.
