Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 989804, here are decompositions:

7 + 989797 = 989804
43 + 989761 = 989804
61 + 989743 = 989804
157 + 989647 = 989804
163 + 989641 = 989804
181 + 989623 = 989804
223 + 989581 = 989804
271 + 989533 = 989804

Showing the first eight; more decompositions exist.
