Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19774, here are decompositions:

11 + 19763 = 19774
23 + 19751 = 19774
47 + 19727 = 19774
113 + 19661 = 19774
191 + 19583 = 19774
197 + 19577 = 19774
233 + 19541 = 19774
311 + 19463 = 19774

Showing the first eight; more decompositions exist.
