Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8636208, here are decompositions:

41 + 8636167 = 8636208
67 + 8636141 = 8636208
71 + 8636137 = 8636208
79 + 8636129 = 8636208
101 + 8636107 = 8636208
127 + 8636081 = 8636208
151 + 8636057 = 8636208
227 + 8635981 = 8636208

Showing the first eight; more decompositions exist.
