Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 985558, here are decompositions:

11 + 985547 = 985558
29 + 985529 = 985558
59 + 985499 = 985558
71 + 985487 = 985558
107 + 985451 = 985558
179 + 985379 = 985558
227 + 985331 = 985558
251 + 985307 = 985558

Showing the first eight; more decompositions exist.
