Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669892, here are decompositions:

13 + 8669879 = 8669892
31 + 8669861 = 8669892
61 + 8669831 = 8669892
71 + 8669821 = 8669892
191 + 8669701 = 8669892
223 + 8669669 = 8669892
241 + 8669651 = 8669892
263 + 8669629 = 8669892

Showing the first eight; more decompositions exist.
