Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669442, here are decompositions:

31 + 8669411 = 8669442
43 + 8669399 = 8669442
53 + 8669389 = 8669442
101 + 8669341 = 8669442
109 + 8669333 = 8669442
113 + 8669329 = 8669442
149 + 8669293 = 8669442
163 + 8669279 = 8669442

Showing the first eight; more decompositions exist.
