Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 519198, here are decompositions:

5 + 519193 = 519198
37 + 519161 = 519198
47 + 519151 = 519198
67 + 519131 = 519198
79 + 519119 = 519198
101 + 519097 = 519198
107 + 519091 = 519198
109 + 519089 = 519198

Showing the first eight; more decompositions exist.
