Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 985556, here are decompositions:

37 + 985519 = 985556
73 + 985483 = 985556
109 + 985447 = 985556
139 + 985417 = 985556
157 + 985399 = 985556
277 + 985279 = 985556
337 + 985219 = 985556
379 + 985177 = 985556

Showing the first eight; more decompositions exist.
