Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 985942, here are decompositions:

5 + 985937 = 985942
71 + 985871 = 985942
233 + 985709 = 985942
239 + 985703 = 985942
263 + 985679 = 985942
311 + 985631 = 985942
443 + 985499 = 985942
449 + 985493 = 985942

Showing the first eight; more decompositions exist.
