Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669930, here are decompositions:

7 + 8669923 = 8669930
19 + 8669911 = 8669930
37 + 8669893 = 8669930
109 + 8669821 = 8669930
163 + 8669767 = 8669930
229 + 8669701 = 8669930
307 + 8669623 = 8669930
337 + 8669593 = 8669930

Showing the first eight; more decompositions exist.
