Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11644, here are decompositions:

11 + 11633 = 11644
23 + 11621 = 11644
47 + 11597 = 11644
173 + 11471 = 11644
197 + 11447 = 11644
233 + 11411 = 11644
251 + 11393 = 11644
293 + 11351 = 11644

Showing the first eight; more decompositions exist.
