Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 986784, here are decompositions:

5 + 986779 = 986784
17 + 986767 = 986784
47 + 986737 = 986784
67 + 986717 = 986784
151 + 986633 = 986784
167 + 986617 = 986784
191 + 986593 = 986784
241 + 986543 = 986784

Showing the first eight; more decompositions exist.
