Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8666364, here are decompositions:

13 + 8666351 = 8666364
17 + 8666347 = 8666364
37 + 8666327 = 8666364
41 + 8666323 = 8666364
73 + 8666291 = 8666364
127 + 8666237 = 8666364
163 + 8666201 = 8666364
181 + 8666183 = 8666364

Showing the first eight; more decompositions exist.
