Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8684018, here are decompositions:

331 + 8683687 = 8684018
337 + 8683681 = 8684018
379 + 8683639 = 8684018
487 + 8683531 = 8684018
691 + 8683327 = 8684018
709 + 8683309 = 8684018
757 + 8683261 = 8684018
769 + 8683249 = 8684018

Showing the first eight; more decompositions exist.
