Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20020, here are decompositions:

23 + 19997 = 20020
29 + 19991 = 20020
41 + 19979 = 20020
47 + 19973 = 20020
59 + 19961 = 20020
71 + 19949 = 20020
83 + 19937 = 20020
101 + 19919 = 20020

Showing the first eight; more decompositions exist.
