Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 985378, here are decompositions:

47 + 985331 = 985378
71 + 985307 = 985378
101 + 985277 = 985378
197 + 985181 = 985378
227 + 985151 = 985378
257 + 985121 = 985378
269 + 985109 = 985378
281 + 985097 = 985378

Showing the first eight; more decompositions exist.
