Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19556, here are decompositions:

3 + 19553 = 19556
13 + 19543 = 19556
67 + 19489 = 19556
73 + 19483 = 19556
79 + 19477 = 19556
109 + 19447 = 19556
127 + 19429 = 19556
139 + 19417 = 19556

Showing the first eight; more decompositions exist.
