Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 985540, here are decompositions:

11 + 985529 = 985540
41 + 985499 = 985540
47 + 985493 = 985540
53 + 985487 = 985540
89 + 985451 = 985540
107 + 985433 = 985540
137 + 985403 = 985540
233 + 985307 = 985540

Showing the first eight; more decompositions exist.
