Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8673644, here are decompositions:

43 + 8673601 = 8673644
73 + 8673571 = 8673644
97 + 8673547 = 8673644
127 + 8673517 = 8673644
181 + 8673463 = 8673644
211 + 8673433 = 8673644
223 + 8673421 = 8673644
271 + 8673373 = 8673644

Showing the first eight; more decompositions exist.
