Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8666394, here are decompositions:

7 + 8666387 = 8666394
13 + 8666381 = 8666394
43 + 8666351 = 8666394
47 + 8666347 = 8666394
67 + 8666327 = 8666394
71 + 8666323 = 8666394
103 + 8666291 = 8666394
157 + 8666237 = 8666394

Showing the first eight; more decompositions exist.
