Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 102020, here are decompositions:

7 + 102013 = 102020
19 + 102001 = 102020
43 + 101977 = 102020
103 + 101917 = 102020
151 + 101869 = 102020
157 + 101863 = 102020
181 + 101839 = 102020
223 + 101797 = 102020

Showing the first eight; more decompositions exist.
