Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669558, here are decompositions:

31 + 8669527 = 8669558
229 + 8669329 = 8669558
241 + 8669317 = 8669558
307 + 8669251 = 8669558
379 + 8669179 = 8669558
487 + 8669071 = 8669558
607 + 8668951 = 8669558
661 + 8668897 = 8669558

Showing the first eight; more decompositions exist.
