Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8666336, here are decompositions:

13 + 8666323 = 8666336
67 + 8666269 = 8666336
163 + 8666173 = 8666336
199 + 8666137 = 8666336
277 + 8666059 = 8666336
313 + 8666023 = 8666336
337 + 8665999 = 8666336
397 + 8665939 = 8666336

Showing the first eight; more decompositions exist.
