Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668550, here are decompositions:

3 + 8668547 = 8668550
31 + 8668519 = 8668550
61 + 8668489 = 8668550
67 + 8668483 = 8668550
127 + 8668423 = 8668550
181 + 8668369 = 8668550
193 + 8668357 = 8668550
271 + 8668279 = 8668550

Showing the first eight; more decompositions exist.
