Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8684020, here are decompositions:

11 + 8684009 = 8684020
17 + 8684003 = 8684020
113 + 8683907 = 8684020
167 + 8683853 = 8684020
197 + 8683823 = 8684020
227 + 8683793 = 8684020
239 + 8683781 = 8684020
251 + 8683769 = 8684020

Showing the first eight; more decompositions exist.
