Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65560, here are decompositions:

3 + 65557 = 65560
17 + 65543 = 65560
23 + 65537 = 65560
41 + 65519 = 65560
113 + 65447 = 65560
137 + 65423 = 65560
167 + 65393 = 65560
179 + 65381 = 65560

Showing the first eight; more decompositions exist.
