Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669222, here are decompositions:

43 + 8669179 = 8669222
109 + 8669113 = 8669222
139 + 8669083 = 8669222
151 + 8669071 = 8669222
181 + 8669041 = 8669222
229 + 8668993 = 8669222
271 + 8668951 = 8669222
349 + 8668873 = 8669222

Showing the first eight; more decompositions exist.
