Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669622, here are decompositions:

11 + 8669611 = 8669622
29 + 8669593 = 8669622
79 + 8669543 = 8669622
109 + 8669513 = 8669622
139 + 8669483 = 8669622
179 + 8669443 = 8669622
211 + 8669411 = 8669622
223 + 8669399 = 8669622

Showing the first eight; more decompositions exist.
