Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639876, here are decompositions:

13 + 8639863 = 8639876
67 + 8639809 = 8639876
73 + 8639803 = 8639876
79 + 8639797 = 8639876
97 + 8639779 = 8639876
103 + 8639773 = 8639876
127 + 8639749 = 8639876
163 + 8639713 = 8639876

Showing the first eight; more decompositions exist.
