Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 523644, here are decompositions:

5 + 523639 = 523644
7 + 523637 = 523644
13 + 523631 = 523644
41 + 523603 = 523644
47 + 523597 = 523644
67 + 523577 = 523644
71 + 523573 = 523644
73 + 523571 = 523644

Showing the first eight; more decompositions exist.
