Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639356, here are decompositions:

83 + 8639273 = 8639356
107 + 8639249 = 8639356
137 + 8639219 = 8639356
149 + 8639207 = 8639356
179 + 8639177 = 8639356
233 + 8639123 = 8639356
293 + 8639063 = 8639356
359 + 8638997 = 8639356

Showing the first eight; more decompositions exist.
