Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8636278, here are decompositions:

17 + 8636261 = 8636278
41 + 8636237 = 8636278
59 + 8636219 = 8636278
137 + 8636141 = 8636278
149 + 8636129 = 8636278
191 + 8636087 = 8636278
197 + 8636081 = 8636278
239 + 8636039 = 8636278

Showing the first eight; more decompositions exist.
