Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8666404, here are decompositions:

11 + 8666393 = 8666404
17 + 8666387 = 8666404
23 + 8666381 = 8666404
53 + 8666351 = 8666404
113 + 8666291 = 8666404
167 + 8666237 = 8666404
251 + 8666153 = 8666404
311 + 8666093 = 8666404

Showing the first eight; more decompositions exist.
