Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8636340, here are decompositions:

71 + 8636269 = 8636340
79 + 8636261 = 8636340
101 + 8636239 = 8636340
103 + 8636237 = 8636340
173 + 8636167 = 8636340
199 + 8636141 = 8636340
211 + 8636129 = 8636340
233 + 8636107 = 8636340

Showing the first eight; more decompositions exist.
