Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 969644, here are decompositions:

3 + 969641 = 969644
7 + 969637 = 969644
163 + 969481 = 969644
211 + 969433 = 969644
223 + 969421 = 969644
241 + 969403 = 969644
373 + 969271 = 969644
463 + 969181 = 969644

Showing the first eight; more decompositions exist.
