Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668322, here are decompositions:

43 + 8668279 = 8668322
181 + 8668141 = 8668322
211 + 8668111 = 8668322
241 + 8668081 = 8668322
349 + 8667973 = 8668322
373 + 8667949 = 8668322
409 + 8667913 = 8668322
601 + 8667721 = 8668322

Showing the first eight; more decompositions exist.
