Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 578198, here are decompositions:

7 + 578191 = 578198
31 + 578167 = 578198
67 + 578131 = 578198
151 + 578047 = 578198
157 + 578041 = 578198
241 + 577957 = 578198
331 + 577867 = 578198
349 + 577849 = 578198

Showing the first eight; more decompositions exist.
