Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19576, here are decompositions:

5 + 19571 = 19576
17 + 19559 = 19576
23 + 19553 = 19576
107 + 19469 = 19576
113 + 19463 = 19576
149 + 19427 = 19576
173 + 19403 = 19576
197 + 19379 = 19576

Showing the first eight; more decompositions exist.
