Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8636970, here are decompositions:

11 + 8636959 = 8636970
47 + 8636923 = 8636970
53 + 8636917 = 8636970
59 + 8636911 = 8636970
61 + 8636909 = 8636970
71 + 8636899 = 8636970
101 + 8636869 = 8636970
113 + 8636857 = 8636970

Showing the first eight; more decompositions exist.
