Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8684418, here are decompositions:

7 + 8684411 = 8684418
11 + 8684407 = 8684418
59 + 8684359 = 8684418
89 + 8684329 = 8684418
139 + 8684279 = 8684418
151 + 8684267 = 8684418
157 + 8684261 = 8684418
229 + 8684189 = 8684418

Showing the first eight; more decompositions exist.
