Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8686558, here are decompositions:

29 + 8686529 = 8686558
59 + 8686499 = 8686558
71 + 8686487 = 8686558
137 + 8686421 = 8686558
149 + 8686409 = 8686558
197 + 8686361 = 8686558
281 + 8686277 = 8686558
317 + 8686241 = 8686558

Showing the first eight; more decompositions exist.
