Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 985442, here are decompositions:

43 + 985399 = 985442
103 + 985339 = 985442
151 + 985291 = 985442
163 + 985279 = 985442
223 + 985219 = 985442
229 + 985213 = 985442
313 + 985129 = 985442
379 + 985063 = 985442

Showing the first eight; more decompositions exist.
