Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 989890, here are decompositions:

3 + 989887 = 989890
17 + 989873 = 989890
53 + 989837 = 989890
59 + 989831 = 989890
107 + 989783 = 989890
113 + 989777 = 989890
137 + 989753 = 989890
227 + 989663 = 989890

Showing the first eight; more decompositions exist.
