Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65644, here are decompositions:

11 + 65633 = 65644
101 + 65543 = 65644
107 + 65537 = 65644
197 + 65447 = 65644
251 + 65393 = 65644
263 + 65381 = 65644
317 + 65327 = 65644
431 + 65213 = 65644

Showing the first eight; more decompositions exist.
