Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 512258, here are decompositions:

7 + 512251 = 512258
157 + 512101 = 512258
199 + 512059 = 512258
211 + 512047 = 512258
349 + 511909 = 512258
367 + 511891 = 512258
457 + 511801 = 512258
547 + 511711 = 512258

Showing the first eight; more decompositions exist.
