Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19744, here are decompositions:

5 + 19739 = 19744
17 + 19727 = 19744
47 + 19697 = 19744
83 + 19661 = 19744
167 + 19577 = 19744
173 + 19571 = 19744
191 + 19553 = 19744
281 + 19463 = 19744

Showing the first eight; more decompositions exist.
