Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19788, here are decompositions:

11 + 19777 = 19788
29 + 19759 = 19788
37 + 19751 = 19788
61 + 19727 = 19788
71 + 19717 = 19788
79 + 19709 = 19788
89 + 19699 = 19788
101 + 19687 = 19788

Showing the first eight; more decompositions exist.
