Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8684428, here are decompositions:

17 + 8684411 = 8684428
149 + 8684279 = 8684428
167 + 8684261 = 8684428
197 + 8684231 = 8684428
227 + 8684201 = 8684428
239 + 8684189 = 8684428
251 + 8684177 = 8684428
257 + 8684171 = 8684428

Showing the first eight; more decompositions exist.
