Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 578258, here are decompositions:

7 + 578251 = 578258
67 + 578191 = 578258
127 + 578131 = 578258
181 + 578077 = 578258
211 + 578047 = 578258
229 + 578029 = 578258
277 + 577981 = 578258
349 + 577909 = 578258

Showing the first eight; more decompositions exist.
