Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1043644, here are decompositions:

5 + 1043639 = 1043644
47 + 1043597 = 1043644
53 + 1043591 = 1043644
101 + 1043543 = 1043644
113 + 1043531 = 1043644
131 + 1043513 = 1043644
191 + 1043453 = 1043644
293 + 1043351 = 1043644

Showing the first eight; more decompositions exist.
