Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 986724, here are decompositions:

5 + 986719 = 986724
7 + 986717 = 986724
17 + 986707 = 986724
31 + 986693 = 986724
83 + 986641 = 986724
107 + 986617 = 986724
127 + 986597 = 986724
131 + 986593 = 986724

Showing the first eight; more decompositions exist.
