Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669266, here are decompositions:

17 + 8669249 = 8669266
29 + 8669237 = 8669266
59 + 8669207 = 8669266
107 + 8669159 = 8669266
149 + 8669117 = 8669266
239 + 8669027 = 8669266
293 + 8668973 = 8669266
449 + 8668817 = 8669266

Showing the first eight; more decompositions exist.
