Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72020, here are decompositions:

37 + 71983 = 72020
73 + 71947 = 72020
79 + 71941 = 72020
103 + 71917 = 72020
139 + 71881 = 72020
199 + 71821 = 72020
211 + 71809 = 72020
307 + 71713 = 72020

Showing the first eight; more decompositions exist.
