Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669418, here are decompositions:

7 + 8669411 = 8669418
19 + 8669399 = 8669418
29 + 8669389 = 8669418
67 + 8669351 = 8669418
89 + 8669329 = 8669418
101 + 8669317 = 8669418
139 + 8669279 = 8669418
167 + 8669251 = 8669418

Showing the first eight; more decompositions exist.
