Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990016, here are decompositions:

3 + 990013 = 990016
17 + 989999 = 990016
107 + 989909 = 990016
179 + 989837 = 990016
233 + 989783 = 990016
239 + 989777 = 990016
263 + 989753 = 990016
353 + 989663 = 990016

Showing the first eight; more decompositions exist.
