Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 985220, here are decompositions:

7 + 985213 = 985220
43 + 985177 = 985220
157 + 985063 = 985220
163 + 985057 = 985220
193 + 985027 = 985220
307 + 984913 = 985220
367 + 984853 = 985220
373 + 984847 = 985220

Showing the first eight; more decompositions exist.
