Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25760, here are decompositions:

13 + 25747 = 25760
19 + 25741 = 25760
43 + 25717 = 25760
67 + 25693 = 25760
103 + 25657 = 25760
127 + 25633 = 25760
139 + 25621 = 25760
151 + 25609 = 25760

Showing the first eight; more decompositions exist.
