Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8686940, here are decompositions:

211 + 8686729 = 8686940
271 + 8686669 = 8686940
373 + 8686567 = 8686940
439 + 8686501 = 8686940
571 + 8686369 = 8686940
631 + 8686309 = 8686940
643 + 8686297 = 8686940
727 + 8686213 = 8686940

Showing the first eight; more decompositions exist.
