Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8684424, here are decompositions:

5 + 8684419 = 8684424
13 + 8684411 = 8684424
17 + 8684407 = 8684424
83 + 8684341 = 8684424
157 + 8684267 = 8684424
163 + 8684261 = 8684424
167 + 8684257 = 8684424
181 + 8684243 = 8684424

Showing the first eight; more decompositions exist.
