Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19726, here are decompositions:

17 + 19709 = 19726
29 + 19697 = 19726
149 + 19577 = 19726
167 + 19559 = 19726
173 + 19553 = 19726
257 + 19469 = 19726
263 + 19463 = 19726
269 + 19457 = 19726

Showing the first eight; more decompositions exist.
