Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515198, here are decompositions:

7 + 515191 = 515198
109 + 515089 = 515198
157 + 515041 = 515198
331 + 514867 = 515198
367 + 514831 = 515198
379 + 514819 = 515198
457 + 514741 = 515198
487 + 514711 = 515198

Showing the first eight; more decompositions exist.
