Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1012644, here are decompositions:

7 + 1012637 = 1012644
11 + 1012633 = 1012644
13 + 1012631 = 1012644
43 + 1012601 = 1012644
47 + 1012597 = 1012644
53 + 1012591 = 1012644
71 + 1012573 = 1012644
97 + 1012547 = 1012644

Showing the first eight; more decompositions exist.
