Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669868, here are decompositions:

7 + 8669861 = 8669868
37 + 8669831 = 8669868
47 + 8669821 = 8669868
101 + 8669767 = 8669868
167 + 8669701 = 8669868
197 + 8669671 = 8669868
199 + 8669669 = 8669868
211 + 8669657 = 8669868

Showing the first eight; more decompositions exist.
