Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19564, here are decompositions:

5 + 19559 = 19564
11 + 19553 = 19564
23 + 19541 = 19564
101 + 19463 = 19564
107 + 19457 = 19564
131 + 19433 = 19564
137 + 19427 = 19564
173 + 19391 = 19564

Showing the first eight; more decompositions exist.
