Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8684120, here are decompositions:

13 + 8684107 = 8684120
31 + 8684089 = 8684120
43 + 8684077 = 8684120
73 + 8684047 = 8684120
97 + 8684023 = 8684120
223 + 8683897 = 8684120
337 + 8683783 = 8684120
397 + 8683723 = 8684120

Showing the first eight; more decompositions exist.
