Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647368, here are decompositions:

19 + 8647349 = 8647368
137 + 8647231 = 8647368
139 + 8647229 = 8647368
211 + 8647157 = 8647368
229 + 8647139 = 8647368
239 + 8647129 = 8647368
241 + 8647127 = 8647368
277 + 8647091 = 8647368

Showing the first eight; more decompositions exist.
