Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 68536, here are decompositions:

5 + 68531 = 68536
29 + 68507 = 68536
47 + 68489 = 68536
53 + 68483 = 68536
59 + 68477 = 68536
89 + 68447 = 68536
137 + 68399 = 68536
257 + 68279 = 68536

Showing the first eight; more decompositions exist.
