Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64888, here are decompositions:

11 + 64877 = 64888
17 + 64871 = 64888
71 + 64817 = 64888
107 + 64781 = 64888
179 + 64709 = 64888
227 + 64661 = 64888
311 + 64577 = 64888
389 + 64499 = 64888

Showing the first eight; more decompositions exist.
