Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6560, here are decompositions:

7 + 6553 = 6560
13 + 6547 = 6560
31 + 6529 = 6560
79 + 6481 = 6560
109 + 6451 = 6560
139 + 6421 = 6560
163 + 6397 = 6560
181 + 6379 = 6560

Showing the first eight; more decompositions exist.
