Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8684970, here are decompositions:

11 + 8684959 = 8684970
23 + 8684947 = 8684970
29 + 8684941 = 8684970
31 + 8684939 = 8684970
59 + 8684911 = 8684970
67 + 8684903 = 8684970
97 + 8684873 = 8684970
109 + 8684861 = 8684970

Showing the first eight; more decompositions exist.
