Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639810, here are decompositions:

7 + 8639803 = 8639810
13 + 8639797 = 8639810
31 + 8639779 = 8639810
37 + 8639773 = 8639810
61 + 8639749 = 8639810
97 + 8639713 = 8639810
163 + 8639647 = 8639810
211 + 8639599 = 8639810

Showing the first eight; more decompositions exist.
