Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8666436, here are decompositions:

5 + 8666431 = 8666436
17 + 8666419 = 8666436
19 + 8666417 = 8666436
43 + 8666393 = 8666436
67 + 8666369 = 8666436
89 + 8666347 = 8666436
109 + 8666327 = 8666436
113 + 8666323 = 8666436

Showing the first eight; more decompositions exist.
