Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19976, here are decompositions:

3 + 19973 = 19976
13 + 19963 = 19976
109 + 19867 = 19976
157 + 19819 = 19976
163 + 19813 = 19976
199 + 19777 = 19976
223 + 19753 = 19976
277 + 19699 = 19976

Showing the first eight; more decompositions exist.
