Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997968, here are decompositions:

5 + 997963 = 997968
7 + 997961 = 997968
19 + 997949 = 997968
71 + 997897 = 997968
79 + 997889 = 997968
89 + 997879 = 997968
157 + 997811 = 997968
199 + 997769 = 997968

Showing the first eight; more decompositions exist.
