Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 985438, here are decompositions:

5 + 985433 = 985438
59 + 985379 = 985438
107 + 985331 = 985438
131 + 985307 = 985438
137 + 985301 = 985438
257 + 985181 = 985438
317 + 985121 = 985438
359 + 985079 = 985438

Showing the first eight; more decompositions exist.
