Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647322, here are decompositions:

139 + 8647183 = 8647322
193 + 8647129 = 8647322
199 + 8647123 = 8647322
373 + 8646949 = 8647322
379 + 8646943 = 8647322
433 + 8646889 = 8647322
499 + 8646823 = 8647322
571 + 8646751 = 8647322

Showing the first eight; more decompositions exist.
