Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 985644, here are decompositions:

5 + 985639 = 985644
13 + 985631 = 985644
31 + 985613 = 985644
43 + 985601 = 985644
47 + 985597 = 985644
73 + 985571 = 985644
97 + 985547 = 985644
113 + 985531 = 985644

Showing the first eight; more decompositions exist.
