Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8664644, here are decompositions:

31 + 8664613 = 8664644
97 + 8664547 = 8664644
127 + 8664517 = 8664644
193 + 8664451 = 8664644
211 + 8664433 = 8664644
223 + 8664421 = 8664644
277 + 8664367 = 8664644
421 + 8664223 = 8664644

Showing the first eight; more decompositions exist.
