Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8636368, here are decompositions:

107 + 8636261 = 8636368
131 + 8636237 = 8636368
149 + 8636219 = 8636368
227 + 8636141 = 8636368
239 + 8636129 = 8636368
281 + 8636087 = 8636368
311 + 8636057 = 8636368
347 + 8636021 = 8636368

Showing the first eight; more decompositions exist.
