Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 989878, here are decompositions:

5 + 989873 = 989878
41 + 989837 = 989878
47 + 989831 = 989878
101 + 989777 = 989878
191 + 989687 = 989878
317 + 989561 = 989878
401 + 989477 = 989878
467 + 989411 = 989878

Showing the first eight; more decompositions exist.
