Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639576, here are decompositions:

13 + 8639563 = 8639576
37 + 8639539 = 8639576
163 + 8639413 = 8639576
229 + 8639347 = 8639576
277 + 8639299 = 8639576
313 + 8639263 = 8639576
349 + 8639227 = 8639576
433 + 8639143 = 8639576

Showing the first eight; more decompositions exist.
