Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669436, here are decompositions:

19 + 8669417 = 8669436
37 + 8669399 = 8669436
43 + 8669393 = 8669436
47 + 8669389 = 8669436
103 + 8669333 = 8669436
107 + 8669329 = 8669436
157 + 8669279 = 8669436
197 + 8669239 = 8669436

Showing the first eight; more decompositions exist.
