Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4644, here are decompositions:

5 + 4639 = 4644
7 + 4637 = 4644
23 + 4621 = 4644
41 + 4603 = 4644
47 + 4597 = 4644
53 + 4591 = 4644
61 + 4583 = 4644
83 + 4561 = 4644

Showing the first eight; more decompositions exist.
