Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669500, here are decompositions:

11 + 8669489 = 8669500
17 + 8669483 = 8669500
23 + 8669477 = 8669500
53 + 8669447 = 8669500
83 + 8669417 = 8669500
89 + 8669411 = 8669500
101 + 8669399 = 8669500
107 + 8669393 = 8669500

Showing the first eight; more decompositions exist.
