Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 989668, here are decompositions:

5 + 989663 = 989668
89 + 989579 = 989668
107 + 989561 = 989668
191 + 989477 = 989668
227 + 989441 = 989668
257 + 989411 = 989668
347 + 989321 = 989668
359 + 989309 = 989668

Showing the first eight; more decompositions exist.
