Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639368, here are decompositions:

5 + 8639363 = 8639368
107 + 8639261 = 8639368
149 + 8639219 = 8639368
191 + 8639177 = 8639368
197 + 8639171 = 8639368
317 + 8639051 = 8639368
401 + 8638967 = 8639368
431 + 8638937 = 8639368

Showing the first eight; more decompositions exist.
