Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669964, here are decompositions:

41 + 8669923 = 8669964
53 + 8669911 = 8669964
67 + 8669897 = 8669964
71 + 8669893 = 8669964
103 + 8669861 = 8669964
197 + 8669767 = 8669964
263 + 8669701 = 8669964
293 + 8669671 = 8669964

Showing the first eight; more decompositions exist.
