Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64000, here are decompositions:

3 + 63997 = 64000
23 + 63977 = 64000
71 + 63929 = 64000
137 + 63863 = 64000
191 + 63809 = 64000
197 + 63803 = 64000
227 + 63773 = 64000
239 + 63761 = 64000

Showing the first eight; more decompositions exist.
