Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19974, here are decompositions:

11 + 19963 = 19974
13 + 19961 = 19974
37 + 19937 = 19974
47 + 19927 = 19974
61 + 19913 = 19974
83 + 19891 = 19974
107 + 19867 = 19974
113 + 19861 = 19974

Showing the first eight; more decompositions exist.
