Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669916, here are decompositions:

5 + 8669911 = 8669916
19 + 8669897 = 8669916
23 + 8669893 = 8669916
37 + 8669879 = 8669916
139 + 8669777 = 8669916
149 + 8669767 = 8669916
293 + 8669623 = 8669916
373 + 8669543 = 8669916

Showing the first eight; more decompositions exist.
