Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 985100, here are decompositions:

3 + 985097 = 985100
37 + 985063 = 985100
43 + 985057 = 985100
73 + 985027 = 985100
97 + 985003 = 985100
223 + 984877 = 985100
241 + 984859 = 985100
283 + 984817 = 985100

Showing the first eight; more decompositions exist.
