Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 985040, here are decompositions:

13 + 985027 = 985040
37 + 985003 = 985040
109 + 984931 = 985040
127 + 984913 = 985040
163 + 984877 = 985040
181 + 984859 = 985040
193 + 984847 = 985040
223 + 984817 = 985040

Showing the first eight; more decompositions exist.
