Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8684144, here are decompositions:

13 + 8684131 = 8684144
37 + 8684107 = 8684144
67 + 8684077 = 8684144
97 + 8684047 = 8684144
211 + 8683933 = 8684144
421 + 8683723 = 8684144
457 + 8683687 = 8684144
463 + 8683681 = 8684144

Showing the first eight; more decompositions exist.
