Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 980440, here are decompositions:

17 + 980423 = 980440
23 + 980417 = 980440
47 + 980393 = 980440
113 + 980327 = 980440
179 + 980261 = 980440
191 + 980249 = 980440
281 + 980159 = 980440
359 + 980081 = 980440

Showing the first eight; more decompositions exist.
