Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51256, here are decompositions:

17 + 51239 = 51256
53 + 51203 = 51256
59 + 51197 = 51256
197 + 51059 = 51256
263 + 50993 = 51256
347 + 50909 = 51256
383 + 50873 = 51256
389 + 50867 = 51256

Showing the first eight; more decompositions exist.
