Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 985688, here are decompositions:

31 + 985657 = 985688
157 + 985531 = 985688
241 + 985447 = 985688
271 + 985417 = 985688
337 + 985351 = 985688
349 + 985339 = 985688
397 + 985291 = 985688
409 + 985279 = 985688

Showing the first eight; more decompositions exist.
