Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 989428, here are decompositions:

5 + 989423 = 989428
17 + 989411 = 989428
47 + 989381 = 989428
101 + 989327 = 989428
107 + 989321 = 989428
149 + 989279 = 989428
179 + 989249 = 989428
197 + 989231 = 989428

Showing the first eight; more decompositions exist.
