Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669970, here are decompositions:

7 + 8669963 = 8669970
31 + 8669939 = 8669970
41 + 8669929 = 8669970
47 + 8669923 = 8669970
59 + 8669911 = 8669970
73 + 8669897 = 8669970
109 + 8669861 = 8669970
139 + 8669831 = 8669970

Showing the first eight; more decompositions exist.
