Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3644, here are decompositions:

7 + 3637 = 3644
13 + 3631 = 3644
31 + 3613 = 3644
37 + 3607 = 3644
61 + 3583 = 3644
73 + 3571 = 3644
97 + 3547 = 3644
103 + 3541 = 3644

Showing the first eight; more decompositions exist.
