Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8684842, here are decompositions:

11 + 8684831 = 8684842
53 + 8684789 = 8684842
59 + 8684783 = 8684842
71 + 8684771 = 8684842
83 + 8684759 = 8684842
149 + 8684693 = 8684842
269 + 8684573 = 8684842
359 + 8684483 = 8684842

Showing the first eight; more decompositions exist.
