Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 512220, here are decompositions:

13 + 512207 = 512220
53 + 512167 = 512220
73 + 512147 = 512220
83 + 512137 = 512220
127 + 512093 = 512220
173 + 512047 = 512220
199 + 512021 = 512220
211 + 512009 = 512220

Showing the first eight; more decompositions exist.
