Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65556, here are decompositions:

5 + 65551 = 65556
13 + 65543 = 65556
17 + 65539 = 65556
19 + 65537 = 65556
37 + 65519 = 65556
59 + 65497 = 65556
107 + 65449 = 65556
109 + 65447 = 65556

Showing the first eight; more decompositions exist.
