Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8684398, here are decompositions:

131 + 8684267 = 8684398
137 + 8684261 = 8684398
167 + 8684231 = 8684398
197 + 8684201 = 8684398
227 + 8684171 = 8684398
251 + 8684147 = 8684398
347 + 8684051 = 8684398
389 + 8684009 = 8684398

Showing the first eight; more decompositions exist.
