Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 985940, here are decompositions:

3 + 985937 = 985940
19 + 985921 = 985940
37 + 985903 = 985940
73 + 985867 = 985940
157 + 985783 = 985940
181 + 985759 = 985940
199 + 985741 = 985940
211 + 985729 = 985940

Showing the first eight; more decompositions exist.
