Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 985984, here are decompositions:

3 + 985981 = 985984
5 + 985979 = 985984
11 + 985973 = 985984
47 + 985937 = 985984
107 + 985877 = 985984
113 + 985871 = 985984
281 + 985703 = 985984
317 + 985667 = 985984

Showing the first eight; more decompositions exist.
