Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 985280, here are decompositions:

3 + 985277 = 985280
61 + 985219 = 985280
67 + 985213 = 985280
103 + 985177 = 985280
151 + 985129 = 985280
223 + 985057 = 985280
277 + 985003 = 985280
349 + 984931 = 985280

Showing the first eight; more decompositions exist.
