Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639850, here are decompositions:

13 + 8639837 = 8639850
31 + 8639819 = 8639850
41 + 8639809 = 8639850
47 + 8639803 = 8639850
53 + 8639797 = 8639850
71 + 8639779 = 8639850
97 + 8639753 = 8639850
101 + 8639749 = 8639850

Showing the first eight; more decompositions exist.
