Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 522020, here are decompositions:

3 + 522017 = 522020
97 + 521923 = 522020
139 + 521881 = 522020
151 + 521869 = 522020
211 + 521809 = 522020
229 + 521791 = 522020
271 + 521749 = 522020
277 + 521743 = 522020

Showing the first eight; more decompositions exist.
