Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20030, here are decompositions:

7 + 20023 = 20030
19 + 20011 = 20030
37 + 19993 = 20030
67 + 19963 = 20030
103 + 19927 = 20030
139 + 19891 = 20030
163 + 19867 = 20030
211 + 19819 = 20030

Showing the first eight; more decompositions exist.
