Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 989656, here are decompositions:

149 + 989507 = 989656
179 + 989477 = 989656
233 + 989423 = 989656
347 + 989309 = 989656
557 + 989099 = 989656
677 + 988979 = 989656
719 + 988937 = 989656
797 + 988859 = 989656

Showing the first eight; more decompositions exist.
