Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639936, here are decompositions:

13 + 8639923 = 8639936
37 + 8639899 = 8639936
73 + 8639863 = 8639936
127 + 8639809 = 8639936
139 + 8639797 = 8639936
157 + 8639779 = 8639936
163 + 8639773 = 8639936
223 + 8639713 = 8639936

Showing the first eight; more decompositions exist.
