Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 985856, here are decompositions:

37 + 985819 = 985856
73 + 985783 = 985856
97 + 985759 = 985856
127 + 985729 = 985856
199 + 985657 = 985856
337 + 985519 = 985856
373 + 985483 = 985856
409 + 985447 = 985856

Showing the first eight; more decompositions exist.
