Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1006644, here are decompositions:

7 + 1006637 = 1006644
11 + 1006633 = 1006644
31 + 1006613 = 1006644
61 + 1006583 = 1006644
97 + 1006547 = 1006644
101 + 1006543 = 1006644
113 + 1006531 = 1006644
131 + 1006513 = 1006644

Showing the first eight; more decompositions exist.
