Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8666340, here are decompositions:

13 + 8666327 = 8666340
17 + 8666323 = 8666340
71 + 8666269 = 8666340
103 + 8666237 = 8666340
139 + 8666201 = 8666340
157 + 8666183 = 8666340
167 + 8666173 = 8666340
173 + 8666167 = 8666340

Showing the first eight; more decompositions exist.
