Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669940, here are decompositions:

11 + 8669929 = 8669940
17 + 8669923 = 8669940
29 + 8669911 = 8669940
43 + 8669897 = 8669940
47 + 8669893 = 8669940
61 + 8669879 = 8669940
79 + 8669861 = 8669940
109 + 8669831 = 8669940

Showing the first eight; more decompositions exist.
