Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51760, here are decompositions:

11 + 51749 = 51760
41 + 51719 = 51760
47 + 51713 = 51760
101 + 51659 = 51760
113 + 51647 = 51760
167 + 51593 = 51760
179 + 51581 = 51760
197 + 51563 = 51760

Showing the first eight; more decompositions exist.
