Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19536, here are decompositions:

5 + 19531 = 19536
29 + 19507 = 19536
47 + 19489 = 19536
53 + 19483 = 19536
59 + 19477 = 19536
67 + 19469 = 19536
73 + 19463 = 19536
79 + 19457 = 19536

Showing the first eight; more decompositions exist.
