Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639248, here are decompositions:

29 + 8639219 = 8639248
41 + 8639207 = 8639248
71 + 8639177 = 8639248
197 + 8639051 = 8639248
251 + 8638997 = 8639248
257 + 8638991 = 8639248
281 + 8638967 = 8639248
311 + 8638937 = 8639248

Showing the first eight; more decompositions exist.
