Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8684772, here are decompositions:

11 + 8684761 = 8684772
13 + 8684759 = 8684772
59 + 8684713 = 8684772
73 + 8684699 = 8684772
79 + 8684693 = 8684772
199 + 8684573 = 8684772
251 + 8684521 = 8684772
269 + 8684503 = 8684772

Showing the first eight; more decompositions exist.
