Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 989570, here are decompositions:

13 + 989557 = 989570
37 + 989533 = 989570
103 + 989467 = 989570
151 + 989419 = 989570
193 + 989377 = 989570
223 + 989347 = 989570
229 + 989341 = 989570
277 + 989293 = 989570

Showing the first eight; more decompositions exist.
