Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19724, here are decompositions:

7 + 19717 = 19724
37 + 19687 = 19724
43 + 19681 = 19724
127 + 19597 = 19724
181 + 19543 = 19724
193 + 19531 = 19724
223 + 19501 = 19724
241 + 19483 = 19724

Showing the first eight; more decompositions exist.
