Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 985724, here are decompositions:

67 + 985657 = 985724
127 + 985597 = 985724
193 + 985531 = 985724
241 + 985483 = 985724
277 + 985447 = 985724
307 + 985417 = 985724
373 + 985351 = 985724
433 + 985291 = 985724

Showing the first eight; more decompositions exist.
