Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 989564, here are decompositions:

3 + 989561 = 989564
7 + 989557 = 989564
31 + 989533 = 989564
97 + 989467 = 989564
211 + 989353 = 989564
223 + 989341 = 989564
241 + 989323 = 989564
271 + 989293 = 989564

Showing the first eight; more decompositions exist.
