Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 989648, here are decompositions:

7 + 989641 = 989648
19 + 989629 = 989648
67 + 989581 = 989648
181 + 989467 = 989648
229 + 989419 = 989648
271 + 989377 = 989648
307 + 989341 = 989648
397 + 989251 = 989648

Showing the first eight; more decompositions exist.
