Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8684436, here are decompositions:

17 + 8684419 = 8684436
29 + 8684407 = 8684436
107 + 8684329 = 8684436
157 + 8684279 = 8684436
179 + 8684257 = 8684436
193 + 8684243 = 8684436
223 + 8684213 = 8684436
263 + 8684173 = 8684436

Showing the first eight; more decompositions exist.
