Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8684400, here are decompositions:

41 + 8684359 = 8684400
59 + 8684341 = 8684400
71 + 8684329 = 8684400
139 + 8684261 = 8684400
157 + 8684243 = 8684400
199 + 8684201 = 8684400
211 + 8684189 = 8684400
223 + 8684177 = 8684400

Showing the first eight; more decompositions exist.
