Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8684920, here are decompositions:

17 + 8684903 = 8684920
47 + 8684873 = 8684920
59 + 8684861 = 8684920
89 + 8684831 = 8684920
131 + 8684789 = 8684920
137 + 8684783 = 8684920
149 + 8684771 = 8684920
173 + 8684747 = 8684920

Showing the first eight; more decompositions exist.
