Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8636412, here are decompositions:

23 + 8636389 = 8636412
149 + 8636263 = 8636412
151 + 8636261 = 8636412
173 + 8636239 = 8636412
193 + 8636219 = 8636412
271 + 8636141 = 8636412
283 + 8636129 = 8636412
331 + 8636081 = 8636412

Showing the first eight; more decompositions exist.
