Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639008, here are decompositions:

11 + 8638997 = 8639008
17 + 8638991 = 8639008
41 + 8638967 = 8639008
71 + 8638937 = 8639008
281 + 8638727 = 8639008
311 + 8638697 = 8639008
317 + 8638691 = 8639008
347 + 8638661 = 8639008

Showing the first eight; more decompositions exist.
