Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 985210, here are decompositions:

29 + 985181 = 985210
59 + 985151 = 985210
89 + 985121 = 985210
101 + 985109 = 985210
113 + 985097 = 985210
131 + 985079 = 985210
197 + 985013 = 985210
251 + 984959 = 985210

Showing the first eight; more decompositions exist.
