Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 989844, here are decompositions:

5 + 989839 = 989844
7 + 989837 = 989844
13 + 989831 = 989844
17 + 989827 = 989844
41 + 989803 = 989844
47 + 989797 = 989844
61 + 989783 = 989844
67 + 989777 = 989844

Showing the first eight; more decompositions exist.
