Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 989678, here are decompositions:

7 + 989671 = 989678
31 + 989647 = 989678
37 + 989641 = 989678
97 + 989581 = 989678
199 + 989479 = 989678
211 + 989467 = 989678
331 + 989347 = 989678
337 + 989341 = 989678

Showing the first eight; more decompositions exist.
