Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 989440, here are decompositions:

17 + 989423 = 989440
29 + 989411 = 989440
59 + 989381 = 989440
113 + 989327 = 989440
131 + 989309 = 989440
191 + 989249 = 989440
269 + 989171 = 989440
317 + 989123 = 989440

Showing the first eight; more decompositions exist.
