Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644550, here are decompositions:

43 + 8644507 = 8644550
73 + 8644477 = 8644550
97 + 8644453 = 8644550
223 + 8644327 = 8644550
307 + 8644243 = 8644550
337 + 8644213 = 8644550
379 + 8644171 = 8644550
631 + 8643919 = 8644550

Showing the first eight; more decompositions exist.
