Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8666396, here are decompositions:

3 + 8666393 = 8666396
73 + 8666323 = 8666396
127 + 8666269 = 8666396
223 + 8666173 = 8666396
229 + 8666167 = 8666396
337 + 8666059 = 8666396
373 + 8666023 = 8666396
379 + 8666017 = 8666396

Showing the first eight; more decompositions exist.
