Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 989718, here are decompositions:

31 + 989687 = 989718
47 + 989671 = 989718
71 + 989647 = 989718
89 + 989629 = 989718
137 + 989581 = 989718
139 + 989579 = 989718
157 + 989561 = 989718
211 + 989507 = 989718

Showing the first eight; more decompositions exist.
