Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 985398, here are decompositions:

19 + 985379 = 985398
47 + 985351 = 985398
59 + 985339 = 985398
67 + 985331 = 985398
97 + 985301 = 985398
107 + 985291 = 985398
179 + 985219 = 985398
269 + 985129 = 985398

Showing the first eight; more decompositions exist.
