Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19926, here are decompositions:

7 + 19919 = 19926
13 + 19913 = 19926
37 + 19889 = 19926
59 + 19867 = 19926
73 + 19853 = 19926
83 + 19843 = 19926
107 + 19819 = 19926
113 + 19813 = 19926

Showing the first eight; more decompositions exist.
