Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8684146, here are decompositions:

47 + 8684099 = 8684146
137 + 8684009 = 8684146
239 + 8683907 = 8684146
269 + 8683877 = 8684146
293 + 8683853 = 8684146
353 + 8683793 = 8684146
389 + 8683757 = 8684146
509 + 8683637 = 8684146

Showing the first eight; more decompositions exist.
