Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20026, here are decompositions:

3 + 20023 = 20026
5 + 20021 = 20026
29 + 19997 = 20026
47 + 19979 = 20026
53 + 19973 = 20026
89 + 19937 = 20026
107 + 19919 = 20026
113 + 19913 = 20026

Showing the first eight; more decompositions exist.
