Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 512222, here are decompositions:

163 + 512059 = 512222
211 + 512011 = 512222
283 + 511939 = 512222
313 + 511909 = 512222
331 + 511891 = 512222
349 + 511873 = 512222
379 + 511843 = 512222
421 + 511801 = 512222

Showing the first eight; more decompositions exist.
