Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511228, here are decompositions:

5 + 511223 = 511228
17 + 511211 = 511228
59 + 511169 = 511228
167 + 511061 = 511228
227 + 511001 = 511228
239 + 510989 = 511228
401 + 510827 = 511228
461 + 510767 = 511228

Showing the first eight; more decompositions exist.
