Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997198, here are decompositions:

47 + 997151 = 997198
89 + 997109 = 997198
101 + 997097 = 997198
107 + 997091 = 997198
179 + 997019 = 997198
197 + 997001 = 997198
311 + 996887 = 997198
317 + 996881 = 997198

Showing the first eight; more decompositions exist.
