Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622644, here are decompositions:

67 + 8622577 = 8622644
157 + 8622487 = 8622644
181 + 8622463 = 8622644
223 + 8622421 = 8622644
271 + 8622373 = 8622644
307 + 8622337 = 8622644
313 + 8622331 = 8622644
337 + 8622307 = 8622644

Showing the first eight; more decompositions exist.
