Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 986806, here are decompositions:

5 + 986801 = 986806
47 + 986759 = 986806
89 + 986717 = 986806
113 + 986693 = 986806
173 + 986633 = 986806
239 + 986567 = 986806
263 + 986543 = 986806
389 + 986417 = 986806

Showing the first eight; more decompositions exist.
