Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 972020, here are decompositions:

3 + 972017 = 972020
19 + 972001 = 972020
31 + 971989 = 972020
43 + 971977 = 972020
61 + 971959 = 972020
103 + 971917 = 972020
157 + 971863 = 972020
163 + 971857 = 972020

Showing the first eight; more decompositions exist.
