Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8636320, here are decompositions:

59 + 8636261 = 8636320
83 + 8636237 = 8636320
101 + 8636219 = 8636320
179 + 8636141 = 8636320
191 + 8636129 = 8636320
197 + 8636123 = 8636320
227 + 8636093 = 8636320
233 + 8636087 = 8636320

Showing the first eight; more decompositions exist.
