Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8636272, here are decompositions:

3 + 8636269 = 8636272
11 + 8636261 = 8636272
53 + 8636219 = 8636272
131 + 8636141 = 8636272
149 + 8636123 = 8636272
179 + 8636093 = 8636272
191 + 8636081 = 8636272
233 + 8636039 = 8636272

Showing the first eight; more decompositions exist.
