Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669490, here are decompositions:

7 + 8669483 = 8669490
13 + 8669477 = 8669490
43 + 8669447 = 8669490
47 + 8669443 = 8669490
73 + 8669417 = 8669490
79 + 8669411 = 8669490
97 + 8669393 = 8669490
101 + 8669389 = 8669490

Showing the first eight; more decompositions exist.
