Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64810, here are decompositions:

17 + 64793 = 64810
29 + 64781 = 64810
47 + 64763 = 64810
101 + 64709 = 64810
131 + 64679 = 64810
149 + 64661 = 64810
197 + 64613 = 64810
233 + 64577 = 64810

Showing the first eight; more decompositions exist.
