Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8666370, here are decompositions:

19 + 8666351 = 8666370
23 + 8666347 = 8666370
43 + 8666327 = 8666370
47 + 8666323 = 8666370
79 + 8666291 = 8666370
101 + 8666269 = 8666370
151 + 8666219 = 8666370
197 + 8666173 = 8666370

Showing the first eight; more decompositions exist.
