Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997960, here are decompositions:

11 + 997949 = 997960
71 + 997889 = 997960
83 + 997877 = 997960
149 + 997811 = 997960
167 + 997793 = 997960
191 + 997769 = 997960
233 + 997727 = 997960
311 + 997649 = 997960

Showing the first eight; more decompositions exist.
