Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 964644, here are decompositions:

7 + 964637 = 964644
61 + 964583 = 964644
67 + 964577 = 964644
73 + 964571 = 964644
113 + 964531 = 964644
127 + 964517 = 964644
137 + 964507 = 964644
181 + 964463 = 964644

Showing the first eight; more decompositions exist.
