Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561198, here are decompositions:

7 + 561191 = 561198
17 + 561181 = 561198
37 + 561161 = 561198
89 + 561109 = 561198
97 + 561101 = 561198
101 + 561097 = 561198
107 + 561091 = 561198
137 + 561061 = 561198

Showing the first eight; more decompositions exist.
