Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 989458, here are decompositions:

17 + 989441 = 989458
47 + 989411 = 989458
131 + 989327 = 989458
137 + 989321 = 989458
149 + 989309 = 989458
179 + 989279 = 989458
227 + 989231 = 989458
359 + 989099 = 989458

Showing the first eight; more decompositions exist.
