Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669844, here are decompositions:

13 + 8669831 = 8669844
23 + 8669821 = 8669844
67 + 8669777 = 8669844
173 + 8669671 = 8669844
193 + 8669651 = 8669844
223 + 8669621 = 8669844
233 + 8669611 = 8669844
251 + 8669593 = 8669844

Showing the first eight; more decompositions exist.
