Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669960, here are decompositions:

31 + 8669929 = 8669960
37 + 8669923 = 8669960
67 + 8669893 = 8669960
139 + 8669821 = 8669960
193 + 8669767 = 8669960
331 + 8669629 = 8669960
337 + 8669623 = 8669960
349 + 8669611 = 8669960

Showing the first eight; more decompositions exist.
