Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8666356, here are decompositions:

5 + 8666351 = 8666356
29 + 8666327 = 8666356
137 + 8666219 = 8666356
173 + 8666183 = 8666356
197 + 8666159 = 8666356
263 + 8666093 = 8666356
383 + 8665973 = 8666356
389 + 8665967 = 8666356

Showing the first eight; more decompositions exist.
