Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669874, here are decompositions:

13 + 8669861 = 8669874
43 + 8669831 = 8669874
53 + 8669821 = 8669874
97 + 8669777 = 8669874
107 + 8669767 = 8669874
173 + 8669701 = 8669874
223 + 8669651 = 8669874
251 + 8669623 = 8669874

Showing the first eight; more decompositions exist.
