Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20068, here are decompositions:

5 + 20063 = 20068
17 + 20051 = 20068
47 + 20021 = 20068
71 + 19997 = 20068
89 + 19979 = 20068
107 + 19961 = 20068
131 + 19937 = 20068
149 + 19919 = 20068

Showing the first eight; more decompositions exist.
