Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10020, here are decompositions:

11 + 10009 = 10020
13 + 10007 = 10020
47 + 9973 = 10020
53 + 9967 = 10020
71 + 9949 = 10020
79 + 9941 = 10020
89 + 9931 = 10020
97 + 9923 = 10020

Showing the first eight; more decompositions exist.
