Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19736, here are decompositions:

19 + 19717 = 19736
37 + 19699 = 19736
127 + 19609 = 19736
139 + 19597 = 19736
193 + 19543 = 19736
229 + 19507 = 19736
307 + 19429 = 19736
313 + 19423 = 19736

Showing the first eight; more decompositions exist.
