Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 512020, here are decompositions:

11 + 512009 = 512020
23 + 511997 = 512020
29 + 511991 = 512020
59 + 511961 = 512020
227 + 511793 = 512020
233 + 511787 = 512020
263 + 511757 = 512020
317 + 511703 = 512020

Showing the first eight; more decompositions exist.
