Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8654920, here are decompositions:

3 + 8654917 = 8654920
23 + 8654897 = 8654920
47 + 8654873 = 8654920
83 + 8654837 = 8654920
149 + 8654771 = 8654920
167 + 8654753 = 8654920
191 + 8654729 = 8654920
257 + 8654663 = 8654920

Showing the first eight; more decompositions exist.
