Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 985140, here are decompositions:

11 + 985129 = 985140
19 + 985121 = 985140
31 + 985109 = 985140
43 + 985097 = 985140
61 + 985079 = 985140
83 + 985057 = 985140
113 + 985027 = 985140
127 + 985013 = 985140

Showing the first eight; more decompositions exist.
