Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997900, here are decompositions:

3 + 997897 = 997900
11 + 997889 = 997900
23 + 997877 = 997900
89 + 997811 = 997900
107 + 997793 = 997900
131 + 997769 = 997900
149 + 997751 = 997900
173 + 997727 = 997900

Showing the first eight; more decompositions exist.
