Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 945644, here are decompositions:

13 + 945631 = 945644
43 + 945601 = 945644
67 + 945577 = 945644
97 + 945547 = 945644
163 + 945481 = 945644
181 + 945463 = 945644
277 + 945367 = 945644
313 + 945331 = 945644

Showing the first eight; more decompositions exist.
