Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8684320, here are decompositions:

41 + 8684279 = 8684320
53 + 8684267 = 8684320
59 + 8684261 = 8684320
89 + 8684231 = 8684320
107 + 8684213 = 8684320
131 + 8684189 = 8684320
149 + 8684171 = 8684320
173 + 8684147 = 8684320

Showing the first eight; more decompositions exist.
