Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669478, here are decompositions:

31 + 8669447 = 8669478
61 + 8669417 = 8669478
67 + 8669411 = 8669478
79 + 8669399 = 8669478
89 + 8669389 = 8669478
127 + 8669351 = 8669478
137 + 8669341 = 8669478
149 + 8669329 = 8669478

Showing the first eight; more decompositions exist.
