Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8666234, here are decompositions:

61 + 8666173 = 8666234
67 + 8666167 = 8666234
97 + 8666137 = 8666234
211 + 8666023 = 8666234
337 + 8665897 = 8666234
457 + 8665777 = 8666234
601 + 8665633 = 8666234
631 + 8665603 = 8666234

Showing the first eight; more decompositions exist.
