Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669556, here are decompositions:

13 + 8669543 = 8669556
29 + 8669527 = 8669556
43 + 8669513 = 8669556
67 + 8669489 = 8669556
73 + 8669483 = 8669556
79 + 8669477 = 8669556
109 + 8669447 = 8669556
113 + 8669443 = 8669556

Showing the first eight; more decompositions exist.
