Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8605558, here are decompositions:

29 + 8605529 = 8605558
47 + 8605511 = 8605558
89 + 8605469 = 8605558
179 + 8605379 = 8605558
197 + 8605361 = 8605558
239 + 8605319 = 8605558
251 + 8605307 = 8605558
317 + 8605241 = 8605558

Showing the first eight; more decompositions exist.
