Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669394, here are decompositions:

5 + 8669389 = 8669394
43 + 8669351 = 8669394
53 + 8669341 = 8669394
61 + 8669333 = 8669394
101 + 8669293 = 8669394
157 + 8669237 = 8669394
271 + 8669123 = 8669394
277 + 8669117 = 8669394

Showing the first eight; more decompositions exist.
