Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997228, here are decompositions:

107 + 997121 = 997228
131 + 997097 = 997228
137 + 997091 = 997228
191 + 997037 = 997228
227 + 997001 = 997228
347 + 996881 = 997228
599 + 996629 = 997228
677 + 996551 = 997228

Showing the first eight; more decompositions exist.
