Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8684388, here are decompositions:

29 + 8684359 = 8684388
47 + 8684341 = 8684388
59 + 8684329 = 8684388
109 + 8684279 = 8684388
127 + 8684261 = 8684388
131 + 8684257 = 8684388
157 + 8684231 = 8684388
199 + 8684189 = 8684388

Showing the first eight; more decompositions exist.
