Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 980566, here are decompositions:

17 + 980549 = 980566
107 + 980459 = 980566
149 + 980417 = 980566
173 + 980393 = 980566
239 + 980327 = 980566
317 + 980249 = 980566
347 + 980219 = 980566
449 + 980117 = 980566

Showing the first eight; more decompositions exist.
