Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 989438, here are decompositions:

19 + 989419 = 989438
61 + 989377 = 989438
97 + 989341 = 989438
199 + 989239 = 989438
367 + 989071 = 989438
379 + 989059 = 989438
409 + 989029 = 989438
487 + 988951 = 989438

Showing the first eight; more decompositions exist.
