Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 985700, here are decompositions:

43 + 985657 = 985700
61 + 985639 = 985700
103 + 985597 = 985700
181 + 985519 = 985700
229 + 985471 = 985700
283 + 985417 = 985700
349 + 985351 = 985700
409 + 985291 = 985700

Showing the first eight; more decompositions exist.
