Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 985144, here are decompositions:

23 + 985121 = 985144
47 + 985097 = 985144
131 + 985013 = 985144
137 + 985007 = 985144
197 + 984947 = 985144
227 + 984917 = 985144
233 + 984911 = 985144
263 + 984881 = 985144

Showing the first eight; more decompositions exist.
