Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669838, here are decompositions:

7 + 8669831 = 8669838
17 + 8669821 = 8669838
61 + 8669777 = 8669838
71 + 8669767 = 8669838
137 + 8669701 = 8669838
167 + 8669671 = 8669838
181 + 8669657 = 8669838
211 + 8669627 = 8669838

Showing the first eight; more decompositions exist.
