Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997948, here are decompositions:

59 + 997889 = 997948
71 + 997877 = 997948
137 + 997811 = 997948
179 + 997769 = 997948
197 + 997751 = 997948
311 + 997637 = 997948
359 + 997589 = 997948
401 + 997547 = 997948

Showing the first eight; more decompositions exist.
