Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997984, here are decompositions:

11 + 997973 = 997984
23 + 997961 = 997984
107 + 997877 = 997984
173 + 997811 = 997984
191 + 997793 = 997984
233 + 997751 = 997984
257 + 997727 = 997984
347 + 997637 = 997984

Showing the first eight; more decompositions exist.
