Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1022020, here are decompositions:

3 + 1022017 = 1022020
47 + 1021973 = 1022020
59 + 1021961 = 1022020
101 + 1021919 = 1022020
113 + 1021907 = 1022020
227 + 1021793 = 1022020
347 + 1021673 = 1022020
359 + 1021661 = 1022020

Showing the first eight; more decompositions exist.
