Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642836, here are decompositions:

17 + 8642819 = 8642836
89 + 8642747 = 8642836
113 + 8642723 = 8642836
269 + 8642567 = 8642836
317 + 8642519 = 8642836
347 + 8642489 = 8642836
383 + 8642453 = 8642836
599 + 8642237 = 8642836

Showing the first eight; more decompositions exist.
