Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 985666, here are decompositions:

53 + 985613 = 985666
137 + 985529 = 985666
167 + 985499 = 985666
173 + 985493 = 985666
179 + 985487 = 985666
233 + 985433 = 985666
263 + 985403 = 985666
359 + 985307 = 985666

Showing the first eight; more decompositions exist.
