Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19764, here are decompositions:

5 + 19759 = 19764
11 + 19753 = 19764
13 + 19751 = 19764
37 + 19727 = 19764
47 + 19717 = 19764
67 + 19697 = 19764
83 + 19681 = 19764
103 + 19661 = 19764

Showing the first eight; more decompositions exist.
