Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 966644, here are decompositions:

13 + 966631 = 966644
31 + 966613 = 966644
61 + 966583 = 966644
97 + 966547 = 966644
163 + 966481 = 966644
181 + 966463 = 966644
271 + 966373 = 966644
307 + 966337 = 966644

Showing the first eight; more decompositions exist.
